Refund and credit on my account not received after 3 months

I had sold my property in August 2017 and visited the Chatsworth branch of Ethewkini Municipality on 12 August 2017 to deregister my consolidated billing account (which includes electricity/water/refuse/rates). It was confirmed that the account was then closed on the system and that I would receive my deposit as well as large credit on my account in 6 to 8 weeks by eft payment into my bank account. I waited for that time and received nothing. In this time since 12 august 2017, Ethekwini Municipality has been deducting monthly rates from my credit owing to me for a property that is already SOLD and account deregistered by the Ethekwini Municipality official,

I then revisited the Chatsworth office on 13 October 2017 but was turned away because I was 2 minutes late and was told by the official at the door that the office "closes" at 11.30am. So much for the Batho Pele principle of serving people.

I have also emailed ethekwini municipality on 2 occassions over a space of 2 months thus far and received an automated response that my query will be addressed within 48 hours and I would be contacted. I have received no response as yet.

This is very frustrating as my credit is being eaten away by rates that does not belong to me for 3 months now, and to add to that fact, I have not recived the refund for my deposit and my credit BEFORE the incorrect rate deduction from my account.

Could someone please revert urgently as I have exhausted all channels of communication in getting this resolved, as the only option I have left is seeking legal counsel as well as going to the media and tabloids.
