Disgusting service and violation of clients POPI rights

In March this year is was contacted by an employee who asked me for a debit order date for my Standard Bank account. I gave him the date and amount to debit to get my account which was just a little overdue. He sent me a confirmation email with another pdf listing all other clients of theirs with the clients addresses, names and contact details. When I informed the same person he said he would look into it. In August I received a call from MBD stating that my account was in arrears as I had missed a few payments! Wheb I told them I spoke to the agent prior they said he had left and must not have captured my information and would look into it. Now my account was in the red as according to them I had missed months of payments which is not the case as I ensured the money was available before and around the debit date. The agent Zodwa informed me she would escalate this matter once again but still has not made contact. I recently app**** fkr vehicle finance and was declined as the company picked up that there is a Judgement on my name for this account which is not my fault but that of MBD! I am struggling as I have contacted the ombudsman, experian and have sent Zodwa numerous emails which she ignores! I am stuck as I cannot do anything due to this apparent judgment and let us not forget about the violation of mine and other individuals POPI rights!
