Pathetic service at Brand Online shop

I bought a microwave online, the website did not indicate that the product is out of stock. I was then called and advised that the microwave is not available and offered other microwaves which i turned down. I then got insulted (F*CK YOU) and told i will be made to wait for my refund for ages. VERY BAD SERVICE. WILL NOT RECOMMEND ANYONE TO BUY FROM THIS SHOP.
