Two weeks later still no order so I began calling the call center agents ,spoke to numerous of them all of which gave different answers regarding my delivery.Long story short ,I have always been a loyal customer to you guys but up to now still have not received my order and no one can advise the true story as too what happened,I then called in two weeks ago to have my money refunded as I could no longer wait for this order.I was told to send through proof of payment and have done that a week ago but still I cannot get my money back. This is a large amount of cash and after all this convenience I have been forced to purchase a bed elsewhere now I need my money refunded asap
