Lost deposit and bad customer service

I deposited R1650 in January 28. To date municipality have not received my payment. I went to bedford branch and have been going up and down for a full month now. Thabo the branch manager never bothered to call me, instead he is not even having conversation with me. I logged a complaint, and the client services claimed they got the copy of my deposit slip and the branch will then call me back with full details. Wilma called me with no knowledge of my complaint. I told her to get her facts in order and call me back with proper solution. She tried to call me once on Thursday last week and never since. I didn't answer the call and no message was left for me. Currently I have tenants and unable to load electricity for them. My account is suspended because of one month in arrears. I have advised them of the urgency of the matter and no one seems to care, except for the consultant either Mbali or Single. She tried to get management involved, instead Thabo was busy with one client 2 hours later then went to a conference call with other staff members. Until today he still has not called me back. I have opened a cheque account, I don't think it was a wise move as I am scared to leave FNB as they do care about our complaints and take them seriously. Money is lost in transit and no one is willing to help.
