worst customer service....

I purchase a mattress on the 4th of October. i was asked to confirmed my delivery address. Order 475572SE. So by the 8th i asked by when can i expect my order and it was Tharwah Mustapha that emailed me. He rep**** back that they are currently waiting on stock. No where when i purchase the mattress it was stating out of stock. i still mention to him that no where on the website it stating that there is no stock. He still mention on the 9th he will let me know. By the 11th i asked again. Any news on stock arriving and then he rep**** i can expect my delivery by the end of this week. i didn't saw on their webpage that i must wait 10 working days. I request and refund on the 11th and i still didn't hear anything back. I even emailed this morning to asked what is the cancellation process. still no response.
