Last debit order to go through on the 25.06.2015. <br> Then on the 25.07.15 they deducted yet another R462.00 from my account - i immediatly called them up and 4 days later still no responce - So i had the debit reversed.

I asked for a letter and to date not received but yet again another debit went 25.11.15 - Please HELP me
