Mattaress warehouse

Good evening I bought a bed with the mattress warehouse some time in 2018 towards the end of the year while I was away on work, the bed was delivered in Bloemfontein nd I only started using the bed 2019 April when I came back from a work mission, I realized that something was not right with the bed and I started communicating with the warehouse and they were not responding to my emails and messages on Facebook...i finally got hold of the this year and it's been 2months of the promising me that they will come check the bed but they are not helping me with anything and they are ignoring my emails I even spoke to the manager but his not helping....mind you it's a Sealy bed which the manufacturer claims it has 10 years warranty, but it feels like am sleeping on a no name bed please help me
