DSTV complaint

I signed up for 24 months at R749 and for 3 months too much as taken even though I received confirmation in February that I would pay the reduced premium rate. I sent +_ 5 emails and got nowhere. I then sent an email saying I wanted to cancel my subscription. Yesterday Penelope called and she said she would renew the contract at R749 for 24 months (even though it was done in February). It seems that even though I have paid R819 up to end May my DSTV has been disconnected. I am livid as with Lockdown, I can't do much else but watch TV.
