Bad service

I've been struggling for the past two months, I have spend so much money calling multichoice. On the 14th of March 2023 I made payment of R409.81 via FNB cellphone banking, this how make payment on monthly basis. To date no one can trace this payment, I have provided you guys with proof of payment and ref number VODS43KD46JK numerous times .My outstanding balance should be R29 because I was supposed to have paid R429. Can someone look into this OR refund my money back ? I'm highly frustrated with the type of the services I'm getting from you
