Dstv (Multichoice) Pay back my money!

Multichoice is only friendly to you when you give them business. When it's time to refund you what they clearly should, they give you the runaround. I made a payment for my uncle's account and made an error. Instead of paying R400 I paid R4000. I requested for a refund and followed all their instructions, repetitively for that matter, and I was told the refund would come. But to this day, from the 9th of May, I'm still being treated like a first time caller. Dstv, I need my R3600 refund please. I'm a cancer patient and that money is desperately needed for medical bills. Shpui die first for you to to realise life is more important than TV? Disgusted by your service. I called in on Friday and was told someone would call me back the sake day. Today is a Sunday, still nothing. You can do better. I want my money!
