Homechoice shocking service delivery

Terrible customer service and protocols from this company. After purchasing an item online and needing the delivery address changed, the address was amended only after dispatching the item. This order should have been placed on hold until delivery details confirmed. Now my parcel has been out on courier for the past 14 days and no one can give me any feedback. Call centre wont transfer my call or give me the number of a superior to escalate the query. I have left numerous messages for someone to phone me back and no one does. Shocking service from Homechoice!!!!!
