Price lock account issues never resolved

I renewed my dstv price lock in Oct 2019, of which we battled for almost 2 weeks to get it working on die extra view and account issues.

Eventually we got it sorted and November and December I got billed R1003 for price lock when I signed up for R899 price lock package. I have phoned in to Dstv on numerous occasions in November and every time I get told that they will escalate it to the price lock accounts department as multi choice can not do anything. Now the December payment went off once again to the amount of R1003. If I login to self help it tells me that my account is R1003 but I signed a price lock agreement for R899. Because I currently pay more then the normal dstv package without price lock. No one seems to contact me or can explain to me why I am paying more then the agreed price. I sign up to price lock because it’s more affordable but it seems like it has more issues and no solution to any problems as dstv multi choice and dstv price lock does not work on the same place or no one contacts you back in order to solve the issues at hand.
