Bad Bad service or should i say no service at all

Purchased a Restonic bed from Mattress Warehouse on 1st Dec 2017 , after 2 months the mattress started making squeaky sound ,I logged a complain with the warehouse and my complain was logged to the supplier the supplier called and told me that they happy to replace my mattress but I must pay a certain fee .the problem arised whenn I asked about the guarantee the supplier told me that my mattress is out of guarantee because it was bought in Feb 2017 and that was not correct they told me they cant help me then I should go back to the warehouse and explain to them I did exactly that called the warehouse I bought my mattress from an email was sent to the supplier again and no response has been received to date no 1 wants to take responsibility between the warehouse and their supplier and solve this all they keep doing is to send emails which are not helping me in any way. Businesses are really quick to sell stuff to us and take our money but they don't wanna take responsibility when it comes to complains This has been going on for almost 4 weeks now and nothing has been resolved except meaningless emails that are not helping I'm still sitting with the same mattress that I'm not happy with.
