Dissapointed and lied to about service

I started a home business in May so I wanted to switch over my home internet from residential to business to avoid going over my data cap with the extra work.  When I called to make the switch I was informed that I should switch my phone from residential as well because it would save me money. I asked the customer service representative if anything would change on the phone service when I made the switch. He said no everything would stay exactly the same but just be billed on the business account. I agreed to move from residential to business.

Instillation happened and thats when the trouble started. I wasn't told I would have to have a modem for the phone and a seperate for the internet. That was fine but I was not told that there were no commercial products that I could purchase to avoid renting these modems. So now the deal at 29.95 just became 12.95 more expensive. I prefer to use my own equipment and the Arris tm 822 that I had on residential worked perfectly fine for both. I then realzed apparantly after the 30 day window had expired that caller ID was no longer coming up on my television. I called to see if that could be fixed and was told that because the phone was separate from the TV account it could not and there was nothing they could do about that. So I figured I would at least try a different route and use the Xfinity connect app for caller ID so I could see who was calling when I was and wasn't at home. This was not working and after logging into the app then calling customer service I was told that the Comcast/Xfinity app does not work for bussiness accounts and Comcast Business has no apps for their accounts. So I called to see if I could switch my phone back to the residential account and was told that an early termination fee would apply. I'm not terminating service. I'm going from one section of your corporation to another. How can it be that it would cost over $800 to switch my phone from business to residential. I'll keep the contract under residential so there really isn't a problem with me leaving to another provider. I was told nothing would change.

I feel lied to about your business phone service by the salseman who was looking for an upsell so said what I wanted to hear. That is poor customer service. I am a long time Comcast subscriber and have convinced my neighbors to switch over to your service from bell south. I won't be doing that again if this can't be rectified.

Thank You
