Poor after sale service delivery

Our insurance company gave us a credit at New World last year to replace items lost in a flood. The Hisense bar fridge we replaced stopped working on the 12th of January 2021 but is still under warrantee. I contacted New World who referred me to Hisense direct who again informed me they do not replace bar fridges - New World need to give me a credit note. A couple of phone calls later, New World promised to contact Hisense to provide them with the necessary credit note. I waited to hear from them and on the 2nd of February contacted them again, spoke to Lerato who obviously did not know any details, she requested the serial number and a copy of the invoice which I sent through the same day to Werner. Its now already end of the week again with no reply of joy. I have requested them to refund me the money in stead of providing me with a credit instore - I really prefer not to use this store at all in future.
