Xfinity Mobile - $25 per line charge keeps showing up after change of address

Hello, I have both Xfinity Mobile and Internet and moved around 2 months ago and updated my service address with Mobile and Internet services. However, the $25 per line charge for not maintaining qualifying Xfinity service with Mobile (TV or Internet) is still present on the latest bill. I've called and messaged Xfinity Mobile chat and connected with agents 7 times now, and so far the billing issue is not resolved. The agents say everything is all right with my account and I am due a credit of the line charges, however it is still showing up. Asking here as I'm not sure how else to proceed even though reached out already to support via phone and chat multiple times. Thank you
