Paid in full and still the oven is broken.

I should have checked Hellopeter before contacting Frank. He has a website called Repairtech / Appliance Repair Technicians in Cape Town but also owns Cool Cat Refrigeration. He charged more than R4k to repair my oven and stove and when he was at my house he and his colleague dropped it on the floor, smashing the front panel of the oven. He insisted on full payment before leaving the house - promising he would come back with a replacement panel. Instead he has stopped responding to my messages and still my oven remains broken. AVOID !!! Reading other reviews online it seems that he does this often and does not offer any professional service.
