False Advertising of prices and stock availability via their online store

Terrible service received when purchasing from their online store

I purchased several products via their online store which stipulated stock availability. on checkout a message was displayed to illustrate that one item was no longer available, so I deleted it from my cart and continues. This means that any item out of stock should have been indicated.

After Purchasing and paying for the products at 9 am I received a call at 1 pm to inform me that one of the items is sold out (which showed stock availability of 5 when purchased it) and another item which they have no stock of but that they will get the stock in 10 days (this item was also in stock when purchasing).

I feel that all the **** advertising is to get buyers to their site and let them purchase multiple other items and never receive all the items which initially got them to the site I will not be purchasing from this store again and will get fully refunded for my current purchase. What a horrible shopping experience
