Will I ever receive my order?...

Still waiting for my order...after I received an sms (after 9am) saying my order will arrive before 5pm I made last minute arrangements to be home to receive it. No one arrived. A week later and no delivery yet. I phoned a few times and the call centre kept saying they will check with the couriers and phone me back...but no one phones back. After my last call to them I was informed that the order is on it's way and will be delivered before the end of the day. Once again I made arrangements for this but no one showed...am starting to think I might never see my paid for items.
