Sold product they don't have on stock.

One of the sales person **** to me and told me that product was in stock, it was being received at that moment.I paid for the product and we agreed that I should come and collect later which didn't happen because they didn't have the stove and told me that I need to wait for product at that time I was will to collect at any of their branches but the could not help me even worse they can't refund me because this would take seven days
