Need service for my closed account

Have been a client for more than 5 years all was well until I lost my job and my account wasn't functional. Recieved smses regarding the account which was on negative and was advised if I dint make deposit before 21st December account will be closed, tried to to log in to.my app and couldn't on the 15th December tried again since I wanted to make a deposit to my surprise the account was closed. Emailed OM to enquire why is the account closed before 21st as stated on the smses never got any convincing response instead was advised that there are looking onto it. Today 20th an amount on R370 was paid into the account from srd went back to them to advise that I need a statement that shows the payment bounced and was told it will be escalated went to.the branch the called the department where I was supposed to.be assisted still nothing.

ALL I WANT FROM OM IS A BANK STATEMENT OF THE PROOF THAT THE MONEY BOUNCED SO I CAN RETRIEVE MY REFUND...IM REALLY DISSAPOUNTED WITH YOUR SERVICE
