Cape refrigeration Pty Ltd came to fix my fridge and it worked for few days then it stopped working I paid them . They told me they will come again but they never did . Its been 4 months now waiting on them they are no longer responding to my msg even on their face book I just want my refund or them to come fix my fridge I will send all the information and conversation between us and proof of payment Hey man. Hope you are well . You came to put a new tank on my fridge on the 27th of December 2023. After 3 days I called you to come back as the fridge had stopped working. You guys came but were not able to solve my problem. Instead you told me it was an electrical problem. You promised to send someone to come fix the problem. Today, 3 months later still nobody has come to our rescue. To make things worse, my wife was blocked from sending messages to this number. I don't know what I need to do because I have lost my patience now.
