Worst billing department, debiting funds and claiming non-payment

Rain has the worst billing department, I have a month to month subscription with them, I registered my profile with ST bank, when they did not find money on this account they went and decided to debit from an account I once paid with, which is not per agreement, while that’s not my biggest frustration, this money they debited R679 went off my account on the 1st of June, to this day this money is nowhere on my account with them, according to them this money has not reflected, I called them multiple times and they still have me the same response, now I had exams coming up and ended up paying an extra R650 to keep the service running, today I get an email saying my issue has been resolved???? How is it resolved when you took my R679 that you are still jot acknowledging receipt of and are only showing the R650 I paid out of desperation, why are you a month to month subscription platform yet debit from multiple accounts? How do you know if that month I was not in need of the services?? You guys are ****mmers, refund me my R678
