Poor service from Makro

I purchased an gym item in November 2022. Online. Turned out that the item was incorrect. I then contacted Makro customer service online to return it. The item was collected and I haven't been refunded to this day. Their reason is that their store in Ottery where it went back to does not stock the item so they could not refund us. There have been numerous calls and emails back and forth with no results.
