Bad service and wrong information

I am so annoyed with DSTV Multi choice, I even have a headache. My time and airtime calling these people since Monday 26.10.2020 and I am still not getting any feedback. They suppose to debit my account, they didnt now I had to make payment which i did and i am told i have an outstanding balance to be paid - i mean where does that amount come from? I been calling but no one can answer - the last agent I spoke to said that she will send an email to her boss for him / her to call me back. I am still waiting from Monday also I have had another complaint but still no one has prioritize this matter to call me back. I feel like cancelling my contract with them - why should this be such a hassle yet the sales agent had given me wrong information also.... This is so FRUSTRATING, especially first time paying client!!!
