Order payment and confirmation received- Cancelled

Hi<br> <br> On the 12th and 14th of September I ordered various items from Toys R us, as they had some really good online specials. I noticed that some of the items were already out of stock (when I tried to order) for example the disney Princess dresses for R49. However I was lucky enough to order a number of the other items, pay and receive confirmations for them. 2 week have since passed with no communications or emails from Toys r Us, I have been checking on the online status for a delivery update. Today I received a phone call that most of the items are not available (out of stock) and they would at some stage send me an email to let me know which items I will not be getting , this is totally unfair as I have already promised my daughters the items :(
