DONE with Capitec!!!

I AM FUMING!!!!!! I took out a loan with Capitec in February and I have been paying it back no problems until today!!! I had R869 in my CAPITEC account that was paid in by my mom to cover my Medical aid debit order BUT Capitec chose to take R359.08 of that TODAY when I have not been paid yet!!! I phoned the first time and a very helpful lady helped me and reversed the order and explained it may happen again to which I said no problem, I'll just phone again. I phoned again, the second lady possibly more helpful than the last, I asked more questions as to why it was happening and again, happily she reversed the charge. No PROMBLEM... Third time it happened, I'm getting a little frustrated now as I'm at work and not allowed to be on my phone I phone again and give the reference number like the previous lady advised, saying the Operator will be able to see what the phone call is in regards to and will then reverse the payment again. Anyway, I call again. The \toll free"number"
