Terrible Support Experience

my internet has been out since 11/14 at appx 9:30am. A technician was here 11/14 and said it was internal wire issue which he could not fix and that xfinity/comcast does not allow them to fix so I would have to find someone to do it, like my apartment complex maintenance. My apartment manager said they do not do that and it should be xfinity/comcast to do it. I called xfinity yesterday and spent an hour mostly on hold with someone who did not seem to know what he was doing. at the end of the call he promised me that the technician scheduled for today 11/15 would resolve the problem. I made it very clear to him that the first tech said it was wiring in the walls from the outside connection to my wall connection. he again "promised" me that the issue would be resolved. you have your calls recorded so you can listen and confirm that your agent made a promise to me. the tech who just left said he didn't know that someone had already come yesterday and didnt know that the issue was the wiring behind the walls. there was absolutely nothing he could do to help me. he called in and had an appointment scheduled with the 3rd party people who complete this kind of work and that appoint is in OVER 2 WEEKS!! That is incredibly unacceptable!!! I work from home and a stable/strong internet connection is required. I do not just pay the bare minimum for service, I pay a hundred dollars per month for faster speeds/better connection and have done so for many years. This entire experience is absolutely unacceptable and will be the reason for me to look for a different provider. I expect to have a credit of at least a month off my service for this TERRIBLE customer service and for you to look for a way to get someone out to my location WITHIN A WEEK.
