Radio Vision Nelspruit a big ****

I took my television to them to get fixed, and they demanded 410.00 upfront payment and promised to fix my TV in a week period. After that, two months past and my TV was not fixed and when I called them to check progress,they told me I must come fetch my TV coz they can't fix it and when I asked for my refund of the 410.00 upfront payment, I was told it's non refundable. So they are a big ****. Never take your TV to them
