Delay in delivery of upgrade deal.

I have been assisted with an upgrade last week and decided on a deal which you had stock of. Calling your center last week and today and i am told today that you do not know when your stock will be received. This is a phone and tablet deal and i just don't understand why you cannot send me the phone before hand seeing that you don't know when you would be receiving stock of the tablet. I even told the consultant that i would pay extra for a double delivery but i was told that it would be impossible. Holding back 1 device awaiting n stock of the other device does not seem to make business sense at all seeing that I am willing to pay for the extra delivery once stock arrives.

Unacceptable!!!
