DSTV BILLING FLACTUATE ON PRICE LOCK

i am on a Price lock but i sometimes pay extra amount within 30 days period to reconnect and consultants can't explain why, now i paid on the 02/02/2022 and today is the 11th they disconnect my subscription, this morning as per DSTV app i was owing R866 i called they changed to R166 i sent Message on Chat they reconnect me and changed amount to R966 due 11/02/2022, Can DST go to my statements from 01 August 2021 to day and check why the billing fluctuates on Price lock contract ,Customer number: ***7, I move my package to Holiday home on the 20th December and they billed me on the 31st December 2021, when i switched back to my residential i was owing before 30th January. Consultants don't even know how to check Transaction history wow. they can escalate than that's it, i have been holding for more than 3 hours with different consultants and they will never return to you they keep you holding until you hang up, never allow DST consultant put you on Hold just drop the call
