AppliancePro is a NO-GO!!!

On 11 December 2018, Mike from AppliancePro arrived promptly to repair our fridge which no longer was getting cold. He unblocked and regassed it and insisted on R850.00 cash payment. At the time we were so happy to have our fridge working again as it would have been way more costly to replace it. Low and behold, not even 2 months later, our fridge is making a terrible pinging sound and it no longer is getting cold again. There I was thinking "oh this is easy, i will just call AppliancePro so that they can fix it for free as surely it is under a warranty/guarantee." Someone answered my call in a friendly manner and asked for me to forward my original invoice. This I emailed 19 February 2019, 1 day after making the phone call. Two days later I still received no correspondence at all. I called again on 22 February 2019 and after explaining my full details, they ended the call. I received a whatsapp from AppliancePro's number saying "hi". I rep**** with a message asking for a refund as my fridge is not working, the message was delivered and read BUT NO RESPONSE. I called again and each time, the call was ended without someone answering it. I tried calling not using whatsapp and it went to voicemail, I left a message requesting someone to please call me regarding my fridge, or to give me a refund or I could report it to the police. I STILL HAVE HAD NO RESPONSE!!! This is outrageous! They have put an address on their invoice, 30 Suction Road, Paarden Eiland. This address does not exist. We have footage of the technician whom introduced himself as Mike on our complex security cameras and the full details of his vehicle. We are going to do our utmost best to get a refund. I am sure whomever this has happened to already would like their money back to use it towards the purchasing of a new fridge and that includes us.
