Inefficient ! Delay in returning a damaged item to the seller

on 15 January I bought a Eay Eay Thing Bugatti Office & Gaming Chair Office Executive Chair online from Makro that was damaged and I initiated a return online.

Courier guy took almost a week to collect the item. They finally collected it on 30 January. When I follow up with makro for my refund, they says the chair is still in transit and has not reached the seller!!!!!!! Really, Courier Guy! Why are you taking that long to return the chair to the seller because this is also affecting my refund. You have ruined what was supposed to be my sons birthday gift with your inefficient service,
