BAD service from HiFi Corp

I ordered a diswasher online, which was supposed to be delivered in 5 working days. It took 4 phone calls on 4 different days to customer support, each time with a promise to get back to me by end of day. I eventually insisted on speaking to manager. He was not helpful. After nearly 3 weeks, they cancelled the order claiming there was not stock. However, the item is still advertised online. Have not received my refund yet. Will never shop with HiFi Corp again
