Horrible customer service for Xfinity MOBILE division

So, I usually dont write reviews, however, I'm so darn frustrated with Xfinity's customer care.

1) I called Xfinity Mobile and Internet  on July 13 to report an outage due to Hurricane Beryl that hit us and we were out of both cellular and wifi network for 4 days - starting July 8 until July 12. I was informed by the customer care rep on July 13th that I would receive a credit of $58.32 for all the four days ($14.58 per day). However, a month later when I have to pay the bill - I see there was no credit applied on those dates. When I called the Xfinity customer care, I was informed by one rep that he would be processing the credit while another extremely rude supervisor Christian wouldn't want to budge and almost called me a liar by saying I had not called in to report about the outage and hence he wouldn't be able to process the credit. All this after I called Xfinity Mobile and confirmed with them twice on July 13 that they would process the credit for my mobile account.

Have called 5-6 times and after waiting through their extremely unrealistic long wait times - waiting 50-55 mins to get a customer care rep to talk to me and then spending two hours of talktime with them - it is extremely frustrating that I still do not have a solution and have to deal with absolutely poor customer care associates who have absolutely no empathy for the end customer and do not provide any constructive solutions.

Xfinity should shut their [Edit: Language] mobile division - as they neither have good reception nor a proper customer service representation.
