Shocking service

Purchased a couch from the Melrose Arch store on 3rd December 2022. Was assured I would receive an email in a few days to schedule delivery of the item. Called their number on 13th Dec to follow up since I had received no communication. A lady assured us she would get back to us. Nothing. Tried calling their store number and helpdesk, no answer. Eventually went to the store personally on 3 Jan 2023. Was again assured someone would call me back to provide feedback since they could not actually trace where the item was. I was very clear that they needed to call me before lunch as I had travel plans. Well..no surprises. Still waiting on that call. So as a last ditch effort, called the store. No answer. I am at a loss what to do now.
