Unfulfilled order: FALSE ADVERTISING

Bought a few items that were advertised at 70% discount, these included a Fossil watch, order was confirmed and showed to being processed for 4days straight on the day which the order was dispatched for delivery I received a message that the watch was removed from the order and refunded due to no stock but the same watch is still being sold by Superbalist now at a higher price than I had purchased but they claim that they have no stock. I even went on their site an added the watch to cart and proceeded with the checkout process, clearly this is a question of false advertising. I am so disappointed, have been buying from them from their days of fashion 360, they have lost a client
