Unreliable

I placed an order for a gift for my sons birthday. I received multiple delivery dates and chose the Saturday for my delivery. I then received a sms confirmation that my order will be delivered by 5pm on Saturday. I waited the whole of Saturday at home to receive the order and guess what, no order was delivered. My son's birthday was ruined and I do not know when I will receive my order. This gift was suppose to come with us on holiday as well. I called the call center and all that they can tell me is that they are awaiting feedback from the DC. Truly disappointed.
