*****ulent debit orders

I was double debited for the Month of May. When calling the contact centre for a resolution, I was then told that I had made an arrangement which again, is utter bull****. After requesting a refund for the bank charges (FNB charges R105 for missed debits) I was then told that I should provide a bank statement and basically ride a unicorn. This is strange and *****ulent behaviour because I was not in arrears and the first debit order was successful on the 27th of May so the second debit order on the 3rd was them being the ****** that they are! They also do not allow you to cancel your membership even when THEY BREACH IT THEMSELVES!
