Delivery/Returns Backlock

Homechoice delivered the wrong items in Dec 2020.....not just any items ( fridges) which are now taking up my space. I requested a return of these items on 17th Dec 2020....to date, the items have still not been collected. Where must I store them?? I phone the customer centre every week and I'm told there's a backlog.... Is that my problem?? I HOPE YOU WON'T BE INVOICING ME FOR THESE ITEMS. COME AND COLLECT YOUR ITEMS PLEASE. I DO NOT HAVE SPACE TO KEEP THEM ANYMORE!
