Credits Discrepancy since Oct-Nov. 2025

When I signed the contract to bring our numbers to Xfinity and replace two old IPhone 13 for two new iPhone 17pro phones, I was promised: $28 and $21 dollars for each phone in credits per month. Plus, as a previous Internet customer, I also was promised to receive $40 in credits (equivalent to one free unlimited line). After taxes and paying for the two iPhone 17pro in instalments, my bill would come to around $95 dollars per month. Instead I am being charged twice as much every month, as credits are not being applied.
