Not receiving my Xfinity mobile new line/ new phone credits

I added my daughter to my account a few months ago under a new line/ new phone plan. Account is on auto pay and I just noticed I haven't been receiving my monthly credits for the new line. The girl at the store, that set it up, had no idea what she was doing. Now I cannot get a live person on phone or chat. This is ridiculous. Your "customer service" is absolute trash. So now I have to report it to PA's consumer protection line. You maybe want to fix this?
