Bad service by wesbank

Money was paid in to an account wrong on the 22 February. On the 5 of March my bank try to get back the money,(R68000) After a lot of emails from my side and false promises that they ask 2 times 48 hours to resolve the problem from the bank,, and the proof that confirm that the money was paid in the wrong account, there is no result. They just ignore my emails and telephone calls do not solve the problem. Of that R68000 only R3000 was paid back. In my career of nearly 44 years with different banks , Wesbank is the most useless bank in South Africa.
