A HUGE INCONVIENCE!!!!!

I made an online purchase from Pedros Hillbrow on Friday the 9th August, the money was deducted from my account and i shortly received a message informing me that my order couldn't be processed. I later got a call from Pedros Hillbrow informing me that the store cant take any orders coz they havent had electricity for a week! Why does Pedros allow us to place an order knowing very well that the store wont be able to fulfill the order??? Still waiting for my credit, i was inconvenienced and will NEVER ORDER from Pedros ever again. Please can you send me my credit of R620!!!!!!
