Useless and poor service

Checkers 60sixty. It has happened numerous times now that we have been invoiced for goods that we have not received not to mention all of the times an item or items you choose is out of stock. POOR POOR POOR, one of the most useless services. They take your money and if you don't realise immediately that something is missing and struggling yourself to death to get hold of someone to log a complaint following a long and tiresome procedure... Then sorry for you... You loose your money. I will never use them again, I would rather walk to the shop to buy food before using them again.
