I'm absolutely furious. The mattress my mother bought has been delivered to the wrong address on the wrong date - entirely their system error. We've been on the phone 4 times to customer service, each time having to wait in a queue for 30 minutes before being able to speak to someone. They have all assured us a) first of all that everything was fine and it wouldn't be delivered incorrectly despite the notification from the (useless, incompetent, rude) DX Delivery courier; b) second that they would resolve the situation ASAP and get the mattress picked up and redelivered. It has been a week and this has not yet happened, despite them knowing she is moving house in a few days and needs the mattress picked up and redelivered before then - or else she will be sleeping on the floor for the next month. We will never, ever buy from them again or from any company that uses DX.
