Checkers Montana ****ming checker 60 customers

On a few occassions i have selected and paid for some items only to find that the item(s) have been removed from the list after payment, but the final checkout amount still reflects a sum that includes those missing items.

At first i thought it was me, but i started taking screen shots of the items and guess what. I was right. There are items that are in the checkout basket and i pay for but are not in the final invoice.
