Non existent service

I had a bedset delivered on 9 August after ordering online, found out the bed had been damaged at the back of the mattress (slash at the back), you can actually see the insides of the mattress. I have emailed both the orders and the customer service emails and so far I have received no word from dialabed.. I phoned the number given and I was told I will be called back and still nothing and it has been a week already. Today that same number is on voicemail. I just need new mattress that's all, and where am I expected to sleep when I got rid of the old bed.
