Un updated direct payments

I took an onair tv contract taking dstv explore contract was supposes to end Dec . It all stated last year April I was told am on areas on R358 then on the 26th I made that payment but to my surprise when I called them asking when my contract will end I was told am on areas of R158 I asked the consultant for which month she checked and said it's for never. I payed again a direct payment of R200 on 6th Dec then emailed it asking them to update the account and send me paid up letter . They promised to do so and never received anything from then. End Jan they deducted my acc and I reversed it in knowledge that I paid them even more than I should have . When trying to contact with them via whatsapp no answer. Today I called them asking why are they still deductingfrom my account agent said am on areas of R358 when I ask him about the direct payments I made he said I must whatspp the proof of payment again I did but it still not updated . Even on credit bureau my account reflect as a bad payer .

All iwant from them is to update the account then send me paid up letter which they are failing to do so
