personal details and payments mixed up with mine

all info on my account been mixed up with a Tsepho. his payments or arrangements coming off my bank account. i have emails where they admit but i have to wait 14 working days for my money back. told them to fix my details and still they cannot pick up my id number. Think they need to be looked into, they could be taking thousands from many customers to solve a cash flow problem temporarily. i pent 3 days with them and still nothing is fixed. confirmed yesterday . I have all my account numbers and all detail but they claim. i must wait. I might need that money for food. i want my money back with interest and or they need to be looked into as i will not put it past them that they might be doing this to many others and we all have to wait 14 days (nice way to have a load of money for 14 working days interest free ) i feel they stole. took it without communicating and it was not meant for me, but Tshepho, even have his cell phone number and id. i am not getting any joy out of this as i cannot call into the call center. they "dont "have my detail or verification questions on file but Tshepho's, so i am blocked out the whole time after calling and you speak to a different person and even if you have the persons name and surname, you still need to know the extension or what province does this person work at. It is a nightmare
