Possible ********** conduct?

I visited the Forever New factory store at Access Park in late September. While paying for my purchases, there was a power failure in the centre. Despite my receiving a sms from my bank indicating the transaction has been authorized, the staff refused to release the goods to me. They continually insisted that the transaction did not go through (because the machine lost power while authorizing the transaction) and I had to leave the store empty handed. I have just returned from a trip, and was horrified to discover that the full amount had been debited from my bank account.<br> <br> As far as I am concerned, this is ***** by the store, and should be seen in a very serious light. I insist on a credit to my account for the full amount as I did not receive the goods from the store.
