Bad customer experience

I made payment arrangements for the 27th of each month however they debited my on the 25th which returns unpaid and I called to inform them and they promised me it’s fixed however it still went off on the 25. I decided to manually pay the account the next thing I know my account was handed over to Blake’s and associates which also messed up my credit profile. I made arrangements with Blake for R500 and they double debit me. They tell me about a refund of 7-14working days which is a mistake that was made on their side. Poor customer service with Agents who hung up the line and giving different advise. I wouldn’t recommend anyone to OnAir.
