Unhappy customer with back pain and headache

I bought one of Coricraft's metal frame beds. When it arrived in a box reading "Made in China", I was already sceptic, as they supposedly manufacture their own furniture (which is why you can't buy anything off the shop floor). On the first night, it's little support legs in the middle broke off. I app**** for an exchange and a new bed was delivered. Same problem again, got another exchange. Same problem again, but now I was obviously looking for a refund, as there was no point in getting a new bed with the same flaw over and over again. This is where the trouble started... First it took them over a month to send an assessor to come and inspect the damaged bed. He confirmed that it was unrepairable, and that it was an obvious design flaw. His report would be in and feedback will come the following Monday. Then nothing happened. After another two weeks I contacted the sales person at the outlet for an answer, and he sent me a screenshot of the assessor's report on their system, with no verdict made. Eventually, I got an anonymous email from their "info@..." address very rudely saying: "This is a courtesy feedback from the superior manager to advise it won't be possible to get the refund but you welcome to re-select the other Bed of the same value if is above the value you need to pay the differences." [sic] I rep**** that this is unacceptable, as I had already gone through exchanges, and I was not willing to now give them more money for another bed with the same design flaws (I went to their outlet store and check all of their beds out), but to no avail. No answer. I contacted the sales person again - he was on leave, couldn't get hold of the store, and told me to contact customer services. Spoke to someone in a call centre who checked my query, promised to escalate the request, and said that I would receive an email. No email has arrived. No one is doing anything. They seem to be wasting time in an attempt to run out the guarantee exchange period. In the mean time, I'm stuck with a massive bed that I can't use, as it is damaging my mattress and my back. So I paid a lot of money for the privilege of keeping a useless piece of s**** metal in my house that I cannot get rid of unless I exchange it for the same thing, or exchange it for something more expensive and spend more money on the same (s)****. I just want my money back so I can go and buy a real bed anywhere else. Coricraft is just disappointing and I don't understand why they are so overpriced and higly recommended when their ratings on this platform suggests I am not the only one with this problem. My next step is invoking the consumer protection act and getting my lawyer involved.
