Inconsiderate and unhelpful

Made a PayShap payment that went to the wrong account even though the beneficiary's details were correct. I approached them to receive assistance so the money could be recalled or sent to the right beneficiary but so far nothing concrete has been done. It has been almost a month of them giving me the run around with barely any results. I even went to the Mall of Africa branch where they promised to escalate the matter, do an investigation and provide feedback to me by last Monday but nothing has happened so far.
