Incorrect Billing

Kindly assist I have paid my Compact package of R508 on the 29th November 25 and attached pop and also received acknowledgement email ref *** which is a proof that I paid on time then on the 01/12/25 my service was suspended I called multichoice to advise them I paid on time and attached pop then they re activated my service to my surprise they are now charging me reconnection fee for December and I am expected to R558.00 and my Compact package is R508 so they are charging me R50 even though I paid on time and received ref that the pop was received it's unfair as that R50 I can buy two loaves of bread for my children not unless their month end on the 29th as I sent pop on the 29th Can they please fix the billing... Thank you
