Payment issue

Good evening, I took out my DStv price lock subscription out in May 2018 .

16 October 2018 I send through an email asking them to please update my banking details, I receive an email confirming my detail have been updated.

November 2018 I moved out of that premises and let DSTV know to please stop the billing as i now did not have a premises to reactivate my dish .

I reactivate my DStv November 2019 I get this sms “Your debit order for DStv was returned by your bank. Please pay R3648.34 asap. Click payat.io/dstv/***1 for payment options or via WhatsApp on ***”

, I made a total payment of R2259 to date this is supposed to be 549 subscription for Jan and 549 subscription for Feb and the rest to be allocated to my arrears . Now the reason I’m in arrears for October and November 2018 how should I be held responsible for this as I received confirmation that my bank details were updated.

Now you ppl are expecting me to pay 519+85+95 ( I’m not even sure what that amount is because my initial agreement was 549) plus the arrears according you DStv is 2910/ 4 months - 727.50 + the above subscription is just over 1300 .

This is ridiculous I need my account looked into form the highest management this needs to be sorted as i have called in numerous times because my dish is always getting put off because you guys are demanding monies from me that’s not correct.
