6 months later I haven't been refunded my money ****** by vodacom

I wrote a review about this matter in December 2016. Vodacom sold me a tablet that suppsed to be on " the house. 5 months later realized that I was being charged R199 per month for the devise. In Jan 2017 I was finally refunded after involving the NCC. In March 2017 I was billed R3900 for an early contract cancellation fee. I queried this with vodacom in April and to date my money is still not paid. I have been speaking to so many different people to sort this out and after involving NCC, Rudzani Lithole was going to sort it out, that was beginning of July. Phoned him every week to follow up with him and nothing was done. Spoke to him 2 weeks ago and said they have finally issued a credit in my vodacom account which I asked that monies should be deposited into my acc. Followed up with him again because still no money in my acc, he said he has released it and asked him if I need to do anything on my side, said no should expect money in my acc in a few days. Phoned customer care and I was told that funds haven't been released because I needed to phone to do that. Last Monday I spoke to Neo who said I should get my money by Friday the 1st Sep, it's the 3rd and still nothing.
