Unsatisfactory service

Hi, I made a transfer to Std bank from fnb account on 25 April 2019, I was told the account number I made a pmt to has been closed, I was told to fill in recall forms of which I did, the 1st form was sent to them on 6 May, the 2nd on 10th May, the 3rd on 15 May, on 22 nd May I went to the branch I was again told to fill in the recall form, this morning I was told application has been declined because I did not sign indemnity form, of which it was a lie it was signed, I then resend, around 10 am I got an email from them saying I should call a call centre to log a missing payment, I told them that I was asked to do 3 weeks ago and they also told me to fill in recall form. I fail to understand why they cannot help me in recovering my money from STD bank because it is clear the account is closed.

Kindly assist me .
