Authorized debit order

South Africa Payment Exchange Company has deducted R 126.69 from my account unauthorized debit order. There is no agreement, I dont know who they are were they got my details from. I have tried to contact them on ********** 750 the lady could not assist me instead she gave me another number to phone which is ********** 375 called Stratton Communication which they dont answer my calls. Its very frustrating as this will affect my credit profile, since I stopped and reversed the debit order.

Anyone please help as these are ***** Companies who take money from people.
