How to remove a cell from your account when it doesn't even show up on your account to remove it yet comcast keeps using it to call me?

@XfinityMarcus​

Theoretically that phone number has now been removed when I called corporate over comcast not fixing the outside line for 7 or 8 months and counting. Then when I called tech support they couldn't find it on my account anymore. We'll see. That is what they told me last time.

That, finally (first call to corporate), put into action someone taking the issue outside line that needs replaced seriously (never mind that at least 4 local techs said that was the problem and supposedly telephone support escalated it along with local techs but the local supervisor only hear about it, or so I was told, after I called corporate for the first time). Then I called corporate again over the lack of credits and the modem issue (see below). Of course then corporate said it was an inside problem and they were closing the case. That was in direct contradiction to what the local tech supervisor told me. Then I called the local tech supervisor who said corporate was dead wrong (as I had been told the previous Friday that they had determined it was a buried outside line coming to the building issue), it was an outside line problem.

The next day local tech showed up and put in a temp outside line which has mostly solved the issue. SIGH. Now the next step is getting credits for all those months and get the modem I had to buy refunded since I couldn't return it to get my old modem back (best buy). The guy at corporate I dealt with said because the problem was in inside one, he wasn't going to give me a letter to give to the apartment owners to tell them what was wrong and they were responsible to fix it, I deserved no credit AND when one of the techs turned off my internet so I bought a new modem thinking that was the issue - it wasn't as the next tech turned it back on and then I couldn't return the modem and get mine I traded in back, the corporate guy said that wasn't comcast's problem, what if I had bought a $2500 modem - seriously? This was the cheapest one on the comcast list the day after cyber monday (which is not the time to buy anything but the comcast guy had turned off my interent and I had been on a hotspot not realizing it until the next day) so I am out $180.99 as well. This is evolving into a small claims court issue along with channel 3 (TV) investigative folks.

Please explain to me why even corporate behaves like they don't care about their customers... actually with a monoploy locally I can't vote with my wallet and so they don't care. 

Why on earth can't comcast solve problems without all the hassles I have had not to mention documenting all the calls and tech people coming out now is running into the second page. AND last Nov 2 the local tech person said it was an outside problem (along with several others since then). Today is Jan 10th. They ran a new temp line earlier this week. I am beyond disgusted. Comcast needs to seriously clean up their customer servicer act. 

PS I am posting this publicly because this is a problem (lack of appropriate customer service help on the first try) that many of us complain about. I want to make this problem publicly known. 

@user_3ly72r​ here is a phone number for corporate (unless they remove that from my post). I have filed complaints there 4 times now and only, finally, yesterday (FEB 1) did they finally, maybe, finish the job. It took calling coporate to begin with to get any action. The problem here turned out to be the entire (main 4 lane) street apartment building and businesses alike. Been that way for monhts. and they didn't fix it earlier for what reason???
