Refund

On 2nd of April Iswapped with my card at pedros Maphumulo due to network I keep trying (2 times) OK... And endup paying with cash.. And if I check my app the money was gone OK I waited as the lady told me to wait.. I waited for 48 hour but still there was no money on acc.. I went there they told me to wait maybe it because it was holidays OK I waited on Wednesdays I called they I should email my bank statement to them.. I did.. I waited for feedback OK Saturday they give me a letter to send it on my bank so that the bank should track the money back to acc cause the finance office didn't receive the money.. OK I went to standard bank with the letter but at standard bank they say they can't track back the money 😔.. It been so long and m out of help I need my 563 rand.. This really **** me off cause now I don't know what to do
