Old mutual banking account

I opened a money account to fast track the story, the envelope ✉️ I got with the card got lost before I downloaded the application (APP), surprisingly there way a deposit of R6000 which made me to contact the customer service to ask for the closure of the card...I was later negatively listed in their ***** category without any opportunities to speak for myself...that is costing me immediately...no access to loans or any form of credit... employment and my life is at stake as i was informed indirectly that my names will be their ***** list for 10 years...I have tried to contact the banking ombudsman as I cant afford the lawyers...
