Faulty defy solar fridge

I bought a defy solar hybrid fridge from mhcworld in Pretoria in 4 Feb 2022. That fridge did not work following its connection l. I took it back to the store after a week. The store refused to take it back and refund. The matter was referred to defy. A technician can out mid March to check the fridge which has a faulty compressor. To date no feedback has been received from defy. I have spoken to Ishmael and Thato/Mbali regarding a refund through Cherryllee from MHC world and still the faulty fridge has not been collected nor my money refunded.
