ACCOUNT GOT MESSED UP WHILE MOVING ADDRESS !! I was promised a refund four different times. i never received it. [Edited]

Long story short I had xfinity Now internet and phone service. i moved into a new address and I used the chat feature to request an address change.And I did let them know that my new house didn't have a coax setup that I would need to have in a technician come out. they said that was totally fine. They said I had to basically cancel the existing service at my old address and sign up for a new service for Xfinity Now at my new address. so I paid forty five dollars, as they told me to. and then she said, go in the app and schedule the technician. The next day so I did, and a guy on the chat told me that with xfinity.Now it's self service, so they don't have technicians.So then I had to cancel the xfinityNow, service and sign up for the Regular internet service.... four separate times I have talked to your agents on the phone.And in the chat and four separate times they told me, I would be getting a refund full refund of that forty five dollars for that month of xfinity.Now that was charged to my card at my new address that was not even eligible at my new address because I had no coax.  no hate or anger against the agents who promised me the refund because i'm sure that they're just doing their job. but every single time they told me, I would get an email confirmation with my refund details that email never came.This has been happening for months.You guys [Edited: "Language"] up my whole account.I've already moved my mobile service to another company.And if I don't get my forty five dollars back, i'm going to be filing a complaint with the better business bureau.
