Worst online shopping experience

Worst online experience ever. They advertise things of which they dont have stock of. I bought a TV of which there was no stock of which i was unaware. There is no communication from them and when I emailed them there was no response. The only time they responded was when I told them to cancel the sale after hearing nothing from them after a week. Then I had to wait almost 8 days for the refund. They dont care about their customer. No communications
