Faulty Appliances no Communication beware

I bought a Hisense french door fridge at the Centurion brancch on the 13th of August 2023 after this they delivered the fridge on 14th . I paid R30000 for this appliance R450 for delivery after 2 days on the 16th the bottom side of the drawers inside the fridge was completely stock due to frozen water and a leak from the water dispenser. I manage to remove the drawers without causing damage and notify their support desk. They told me that it normally takes a few days for the fridge to startup properly with the ice maker. After few days the same problem happend again i phoned them again on the 23rd of August with the same issue they told me as im now over my 7 days cool off period i cannot return this device anymore. And they will send a technician out to repair the device for friday. And someone would call me to make a booking no one has phoned nor booked anything. Whybdo u sell faulty appliances. I would like to get a refund on my purchase or credits so i can buy a appliance that is not faulty. PLEASE CONTACT ME and should this matter be resolved ill gladly change my review
