********** debit orders

Double Black is a company that deducts debit orders of R99.00 from your bank account without permission. I have noticed that debit orders have been going off my account and did not know for what it was. By the time I noticed it, 4 debits went off already. Luckily the bank could reverse the amounts when I complained. The bank helped to trace the number and company for me, but I had to phone them myself. What a nightmare. Durban number ( ********** )- very difficult to get through. The phone will be ringing non- stop without anybody answering. When somebody eventually answers "Double Black" and you state your story, they will say you must call back for the people from Double Black. If you tell them, " but, lady you just answered the phone Double Black" the phone gets switch off in your ear. Then the process starts all over again. I have spent so many trips to the bank for debit order reversals and I spent so much airtime on phone calls to no avail. How do I stop this people from deducting my money? This is really sickening. I am unemployed at the moment and cannot afford this people to ***** my money every month.
