Worst online service ever

The worst experience, they made a mistake with the pricing of the item the item was in my cart for over 2 weeks then I decided let me purchase it paid for the item, 13 days later still shows processing then I asked what is happening with the delivery the next day my order was canceled with the lie supplier has no stock, when I go check they still showing the exact item in stock with a significantly higer price how convenient, I will never buy from them online again. The fact that they don't take accountability for their error is beyond me. Its the lies acknowledge you made an error don't lie.
