CASH DEPOSIT CLAIM

I'm not happy with FNB service i deposited money to the wrong account via ATM on the 23 of october next day i visited the branch at corner Kruis and Commissioner next to carlton center and they asked me to fill a cash deposit form and attach my deposit slip and they told me that t=i must wait for 3 working days for feedback they still need to contact the owner of an account i deposited funds to. i did not recieved anything for about 2 weeks i visited the branch again i was told that the guy who was assisting me is no longer working there i must go to the branch where is is working . i was surprised . this week of which is the 3rd week waiting i visited the branch again on tuesday the guy told me that they are offline he took my details and he promised me to call and provide me with feed back but i have not receive anything from them. im so disappointed with their service
