Repair **** business avoid at all costs

I contact them to repair a refrigerator, they sent out a technician, the technician came to site and tested the appliance and then advised once he replaces the starter, capacitor and relay, the appliance will work, I paid for the full repair, as they requested upfront payment, they then sent the technician back after I made several calls , he came back and then he was watching YouTube videos to wire the new parts which led me to believe that he was not qualified to be repairing refrigerators ,then when he switched it on the parts blew up and the technician said he will come back with new parts he then came back with new parts and the appliance did not work, they office said they will send another technician where he had diagnosed the compressor was shorted he then I will be contacted by the office for a quote for the compressor when it was not initially faulty only after the incorrect wiring had the compressor blown. The office never contacted me again. They don't answer calls and only communicate via email and Whatsapp. When I requested a refund as there was no repair or parts supp****, the owner said he will be happy to explain to a judge why he will not refund me. After researching the coming I will never recommend anyone using this company. Never pay them until the repair is completed or else they will just **** you. The address on the invoice and there actual business address does not correspond as the business is run from a residential property garage. All their positive reviews are from the owner himself.
