Something not so meaty

Last night at about 18:20 I decided to place an online order for a large pizza on the Debonairs Pizza website. I used my card for the transaction which went through and after a minute of the transaction being processed, I got a message which read; Unfortunately Debonairs Pizza Protea Glen was not able to accept your order. The reason given was; "The store cannot accept the order for the requested date and time." I thought that I could maybe try and go to the store myself, so I called the call centre and was told to go to the store where I can pick up the order. I called the store prior to doing so and I was informed that they have not received the funds and I would not be able to pick the order up. So in short, I could not get the meal I had ordered and I was left without funds as Debonairs Pizza will take up to 48 hours to reimburse me. Why is it that after selecting the store I was placing an order from, the purchase was not stopped citing the reasons given to me only after the transaction took place. I am utterly disappointed to say the least and this experience has truly, left a bad taste in my mouth.
