Multicoice dont pay back my refund.

I reported Multichoice previously. Still the issue has not been resolved. I paid for an upgraded decoder 27 March , but I have valid insurance. I should not have paid for the decoder. I queried this and spoke to numerous people. Check previous complaint, and still have not received my refund yet. Every time the matter gets escalated. After I reported on Hello Peter Multichoice contacted me, but yet again it was referred and I have not received my R599 REFUND. I sent documentation through to Cynthia Chauke on 28 April, but still have not heard from them or received any feedback. Pathetic.
