Appliance Repair

My fridge/freezer broke down on a Saturday - I called Appliance Repair and they sent someone 3 hrs later. They gave a massive labour charge quote but assured me that they would fix my fridge once they got the part and there was hardly anything suitable for months due to backorders. The only payment option was by debit card, which I was not informed ahead of time- all of which should ring alarm bells.
One week later, the tech shows up and says the part is not the correct one. After another week, they tell me the part sent to them is still not the right one. I then ask for my money back.
Not only did they ask for the exorbitant labour charge of $280 - supposed to cover the board which was never fitted, they then deducted what they called restocking & shipping fees! And it will take at least one 1 week for me to get a cheque for the paltry sum refunded. Keep in mind - the fridge/freezer WAS NOT REPAIRED and the part was not the right one. Speaking to Victoria and Hasti was fruitless. There seems to be a company policy to fleece anyone who falls into their hands. Forget service or honesty - they have NO idea of what that means.
Why should I pay a restocking fee if the wrong part was sent - TWICE? Did they order the correct part? Did they even order anything?
After this, I contacted Maydone, and the technician actually collected 2 boards directly from the suppliers and was in my home within 3 hours of the call. Yet Appliance Repair claim it took them one week from the suppliers, who sent the wrong part, TWICE! For which I pay a ridiculous restocking and shipping fee. This must be a profitable racket for them. DO NOT USE APPLIANCE REPAIR! You will be fleeced!
