2 years Explora price lock contract over billed until its expiration date.

I have been on an explora price lock of R499 for 2 years since 2020 November.. My last payment was supposed to be in November of 2022. I had so many issues with my account especially after I signed in for this explora contract. Fortunately I completed my contract of 2 years even though I have always been billed higher to my contract. My main issue is the terms of the completed contract.. I am supposed to go back to my old package of compact without being charged R100 extra for the PVR.. but wen I check my account nothing has changed.. I'm stil being billed the same even aftr I completed my contract.. DSTV multichoice please look into this matter and sort out my billing.. and credit me for all this months I have been paying more than my price lock contract.. i wil be going forward with this matter to my attorneys as this is a complete brigde of contract if this matter is not attended to.
