Worst service

The customer service at rain just keeps getting worse. I was billed R1 058.00 yesterday and they cannot even give me a valid explanation. I am being told that it's payment for October and November but I paid for October. If I was owing for October, I clearly would not have internet access or I would be sent payment reminders like they always do. Worse you guys keep trying to debit my account and I'm incurring unnecessary bank charges. I am tired of the bad service from Rain. I requested a voice recording for a call I made and I was told they can't send it to me
