First Aid Appliance Repair

I called First Aid Appliance Repair to order a part for my refrigerator. The technician Alex came out to look at the refrigerator, and he diagnosed the problem as the condenser fan, however, from my knowledge I told him it was not the condenser fan, it was the main pcb (circuit board) which needed replacing. He then agreed and said I was correct. He ordered the part over the phone, and told me it would take 2-3 weeks for delivery and then charged me 50% of the total cost of labour + parts, which was 50% of $500...= $250. This was on October 1, 2015. After 3 weeks, I called customer service and was told the part was back ordered from the vendor and would not be shipped now until November 22. As this date approached, I was then told the part would not be shipped until December 8. By then 2 months had passed. I started to get frustrated as it does NOT take this long to order a part for a refrigerator. Especially a Samsung. Next, I was told December 27, then January 5, and then last week after multiple phone calls, and correspondences I told them to refund my money. It is ridiculous to wait 4 months. And I got the run around continuously.
Many times, the calls never get through and goes directly to their voicemail. I eventually spoke with Oliver, and I told him that I want my refund. He told me that he could order the part from a different vendor and it would take another 3-4 days. Which would mean it would be supposedly delivered the week of January 18. That means that the initial vendor they say they ordered through, never shipped my part at all. And it has been 4 months already! He said that he would have to get approval to give me my refund back. I said I wanted it credited back to my credit card, and he said they only send a cheque back in the mail. Since that conversation on January 14, I have not gotten any phone calls back. I have tried to call every single day to reach Alec (who takes care of refunds) or Oliver and no one is getting back to me. They are avoiding me, and avoiding giving my money back. They have done no service to me, to many people of the public, as Ive reviewed other complaints on BBB and other sites, stating very similar incidences to mine. I was also told if they give me a refund back, they will deduct labour and a 20% restocking fee from the amount I paid. I refuse that completely, and want the entire refund. There is absolutely no way this company will deduct a 20% restocking fee for a part which was not shipped or sent to me, as I was told it would be ordered from a different vendor just last week. And no labour charges for the fact that there was no part ordered to be installed. No technician came out to me to install any part whatsoever. I actually was the one who diagnosed the initial problem with the refrigerator, the technician didn't even do that on October 1st. The amount I paid is what I want refunded on my credit card. I HIGHLY recommend anyone to NEVER go through this company. It will save you a lot of headaches and money if you go somewhere else. This company does not operate correctly and I have a very strong feeling they do this to a lot of people (as shown online) to keep customers money, hoping they will eventually give up, and possibly get a part made someplace cheaper so they pocket the rest of the money. Either way, something is not right with what this company is doing. I will take this further if i do not receive my refund. They don't deserve a cent from me!
