no phone service - no answers - no tech here - no way to remote forward calls???

My butsiness phone and internet went down yesterday as part of a service outage.  Internet came back, not phone.  An hour on the phone yesterday got me nothing except a report that the problem in on Comcast's end, and a tech would be out at 9 AM today to fix it.  Nothing.  at 10:30, began trying to find out the status.  30 minutes going through the automated line, and being told I had a 3 PM appointment that I hadn't confirmed.  Finally got a live person. Had to tell the whole story, give lots of identiying information  - 3 times - as they transferred me around.  Stayed on hodl as someone tried to call the engineer.  Had to call me back.  Theoretically supposed to be here at 1, but I'm not optimistic.

Tried (again) to find a way to remote forward calls to my cell, but no one can tell me how to do this.  The number that is supposed to work for my area doesn't - I just get a message that i don't have access to that service.  Meanwhile, I have no service, and no way to get any.  2nd time since starting new service (almost) October 1.

Of course, all of this is in addition to finding out that 1) there is a $500 install fee I was not informed of, 2) the service is more than twice what I was told it would be, and has to be paid in two separate bills, to two separate addresses, and 3) numerous threats to shut off my service due to failure to credit a payment that I made timely.

I don't see anywhere to go to address any of these issues, but if they are not resolved by the end of the day, I'm switching carriers.
