Cancellation of service and waiting for Refund.

I have cancelled my Eskom service 1 November 2014. I was given the amount of R4,547.33 with a reference no: *** to refund my Deposit, I was told it will take 6 weeks and I had to supply them with bank details. Nothing happened, I phoned regularly just to be referred to a different department. Cancellations knew nothing and so I was referred from consultant to consultant. On the 3rd March 2015 I called again and spoken to Meya, a very friendly consultant. He advised me that everything is in place and he will find out why they have not refunded me by now, almost 5 months later. I again did not hear from them. Please help.
