Failure to secure purchase

Placed multiple orders a week ago and all was in stock.. I kept viewing the progress till day 6 and the system showed all stock still available. Then on the day of delivery they cancel an order for Out of stock... Whhaatt!!

Obviously as soon as you make a purchase they do not follow through to place order.. This is the 2nd horrible experience with them.. Relating the company with Russian Rollet, never knowing if you will be happy with the outcome.
