Incorrect billing&*********** staff

Multichoice billing system is pathetic, i have been receiving Sms that my dstv subscription will be paused due to no payment received, i also receive emails informing me that my showmax subscription has been paused, i phoned dstv I'm sure 5 times in the past two weeks, i phoned to advise them that the sms i got informing me about my monthly premium is wrong, and i told the agent that I'm on premium subscription and that its impossible that I'm going to pay an amount of R551, the agent told me that dstv app**** some discounts etc, i didn't understand but because i assumed he is working there he knows better, i then started receiving sms that my subscription will be paused i phoned again and the lady said she cant see anything and reconnected me, hours later i received an sms saying i have an outstanding balance of R581 and if i dont make payment my subscription will be paused, i then phoned again and then i was advised that i was billed incorrectly(and I'm on debit order surely its not my fault) the lady said she would escalate the matter and multichoice will get in touch within 24hrs i still haven't received any correspondence from multichoice, this morning i received another sms saying my subscription will be paused. Multichoice is very unprofessional they calculate my subscription and debit my account, i saw their error and brought it under their attention and they couldn't sort that out, no one at multichoice can assist me but they are fast to send sms to say they are pausing your subscription, even if it's not your fault I'm now starting to see why people are canceling their multichoice subscription and moving over to other platforms because dstv is more of an inconvenience than pleasure.
