Refund of electricity deposit

Its been a year now, that I am trying to get my refund back. I have called customer care numerous times and everyone that I have spoken to (after being transferred to numerous staff members and holding on for ever) said they will process it. In November Jabhile A Mfikoe, confirmed by mail that it has been send through for payment, I should check back a week later, which I did. But to date, I have not received anything and nobody is responding. How can one get their refund back, or does the Municipality just take it for themselves.<br> <br> Is there anyone at the City of Tshwane Centurion, that is prepared to help me with this?
