No stock

We upgraded our contract on 2-Feb-16, to a HP 15 laptop & modem as advertised in their pamflet (specials that run until 7-Feb-16). They indicated it needs to be ordered but we will receive it before the end of the week. On Friday, the 5th, we enquired and they indicated that they have not received any stock. I have phoned again today and was informed that the status is the same. No indication could be given on when the stock will be received. Surely it is not unfair if a client expects to receive feedback on the delivery date????
