Is there a way to make Comcast Business move to get refund and cancel service without early termination fee other than lawsuit?

I would like Comcast Business to refund some past charges and cancel my service without early termination fee. I appreciate it if someone could advise what could be the effective action for me to take to make them actually move. Comcast Business representative promised to have their manager call me back but I never received a phone call. I know lawsuit can be an option but if there's another option that Comcast Business cannot ignore before starting that, I would like to know that option as well. For example, can reporting fraud to federal trade commission work? Please let me know if you have the experience of solving similar issue with follows. Thank you.

Background:

I originally had the following business service order agreement with my business in Indiana.

ID: 190322329341437
Service Term(Months): 24
Package Name: Starter Internet
Promotional Code: BSEE:SP_$49.95Starter_2yr_WVI
Total Cost: $49.95/month
Customer Signature Date: 03/22/2019

Then when I moved my business to another location in the same zip code, The business service order agreement was renewed as follows.

ID: 23764245
Service Term(Months): 36
Package Name:
Promotional Code:
Total Cost: $69.95/month
Customer Signature Date: 11/09/2019

Then due to Covid-19 pandemic, I lost my client and closed my business then got hired as an employee and moved to Texas on 6/10/2020. The address I moved to has no Comcast Business service per Comcast Business representative but they put $1468.95 of early termination fee on "Disconnect Request Form" to cancel the service when we talked over the phone around 6/10/2020. So I did not sign it and am still paying $69.95/month as of 03/21/2021.

I was busy getting used to the new job working extra time with no payment so could not work on this issue but now that I have some time, I would like to solve this.

Goals:

I consider the following 3 payments unnecessary. So I would like Comcast Business to refund 1), 2) then cancel my service without 3).

1) $20 extra charge occurred since 11/09/2019 until I moved out of Indiana on 6/10/2020. $20 x 7 month = $140
2) Monthly charge of $69.95 since I moved out of Comcast Business service area on 6/10/2020 till today 3/21/2021. $69.95 x 10 month = $699.50
3) Any early termination fee Comcast Business will impose if I request the service cancellation now.

Justification:

• The reason why I consider 1) above as unnecessary is because it was sneaked in when I moved within the same zip code even though I did not ask for any service changes. Comcast Business representative just rushed me to sign the new document sent by email without explaining what's changed over the phone.

• The reason why I consider 3) above as unnecessary is as follows.

The service order agreements above have the following link to refer to the terms and conditions on which a PDF file "SMB TCs v 37.pdf" can be downloaded from a link named "Comcast Business Services Terms of Service for purchases on or after 4/1/2013".

http://business.comcast.com/terms-conditions/index.aspx

From the end of page 1 of the PDF file, termination charges are defined as follows. 

  Termination Charges: Except as otherwise provided herein, charges that may be imposed by Comcast if, prior to the end of the applicable Service Term (a) Comcast terminates Services for cause or (b) Customer terminates any Service without cause.

The rational interpretation of the sentence above is that if a customer terminates a service due to a cause, termination charges should not to be imposed. So I looked for the definition of the "cause" and on page 5 of the same file, the following sentence is written at "5.2 Termination for Cause.".

  (c) A Service Order may be terminated by either party immediately upon notice if the other party has become insolvent or involved in liquidation or termination of its business, or adjudicated bankrupt, or been involved in an assignment for the benefit of its creditors.

It defines "termination of its business" as "Termination for Cause". By combining these 2 sections, customer's closing business is regarded as "Termination for Cause", therefore termination charges should not be imposed. Since I moved out of Comcast Business service area due to closing my business, it should be considered as "Termination for Cause". Therefore, termination charges should not be imposed.

• The reason why I consider 2) as unnecessary is because I already explained the above reason of why early termination fee should not be charged in my case to Comcast Business representative over the phone several times around 6/10/2020. They first tried not to understand my point then eventually promised to have their manger call me back but I never received the phone call. If they called me as promised, the service would have been canceled at that point and charge 2) above did not occur.
