Online orders

When I placed an order online over 10 days ago, there was stock of the item that I required. However after placing & paying for the item, I received an email a few days later advising me that the order was cancelled & were refunding me due to no stock. Trying to get a response from Game's customer care is *@#$ ....... I have called the customer care number a few times, spoken to consultants who have reassured me that they will respond to my email & phone calls concerning the order but alas, nothing has been received. I requested in my mail, either they find the stock from a branch for delivery or I am given a rainbow cheque so when there is stock again, I pay the advertised price. It would seem that the Massmart Group don't respect paying customers
