Afritech tv repairs stay away

States that they repair on-site, took my tv away to fix off site. Stating that cost will be around R2500. Two weeks later phoned and state that the cost is R6850 and that it was repaired already by the china man. Say they charge depending on value of tv. After dodgeing me now for two months still no tv. Bunch of ****** don't deal with them. Invoice doesn't even match name but phone number does.
