Standard Banks failure

Incorrectly paid an incorrect recipient via eft after contacted the bank and was advised to do a recall of funds. The recall was charged not a day later after which I had to multiple number of follow ups over two weeks despite the recall form stating recall verdict between standard bank will take no longer than 3 days. After persisting I finally got a positive response saying the recipients bank account has been closed months ago, almost a year. They gave me further instructions to follow for the refunds to be paid back to me, a month later still nothing despite following the instruction to the letter. Even asked my banker to follow up and the only response Ive received was that its been approved but there is internal issues. I cant beleive that one needs to follow up so much and no one bothers to even send an email about the progress or apologies for the delay. Really disappointing considering I've been their client since 2014.
