ITEM NOT IN STOCK AFTER PAID

Hi This is not the way to do business. How can you advertise a product which is not in stock ? Let me wait from the 18 May then tell me on 27 May item out of stock which i paid for. I want a telephone number of the Manager this morning and a immediate refund of the amount paid. I expect a immediate response The product is still showing on the website,but at a higher price. If you advertise you must deliver Chris Benadie ***
