ACP Credit - Keeps getting incorrectly removed from my account/billing

I have been eligible for the ACP credit for over a year now. Over this past year, on four different occasions, I have had my credit incorrectly removed from my bill. Each time I have called in to speak with customer service and am given a different explanation. Basically they all boil down to Xfinity telling me my credit was transferred to another carrier. This is not true as I have never had another carrier not have I made any changes to my information or transfers of my ACP application/credit. I have now had my credit removed once again and I need assistance with this immediately. I have tried calling to speak with a rep but unfortunately have been given the run around. Xfinity customer service is telling me again that my credit has been transferred to another carrier which it has not. They then direct me to call the ACP to find out where it has been transferred to. The ACP does not assist customers with their billing but I am able to verify with them my eligibility status. After checking with the FCC directly to confirm that I am still approved and my credit was not transferred, I tried calling one last time to speak with Xfinity This resulted in me being transferred to three separate departments and eventually hung up on.

Can someone please assist me with this and also going forward that the credit not be removed?
