Swiss 93 L Single Door Mini Upright Freezer NEVER WORKED - STILL AWAITING A REFUND

I purchased an upright freezer at the end of February 2025 for R 5899. Since we received delivery, the item has not worked. I have logged numerous return requests, I have phoned many times. I then received a Value Express Waybill number and to date, the item has not been collected. This has to be the most frustrating refund request I have ever dealt with. I NEED SOMEONE SENIOR TO SORT THIS OUT.
