Warrantee claim on bed

I sent them an email in June 2018 to enquirer about a 15 year warrantee on my king size bed - the bed has not lasted at all and feels like its falling apart. We are no in November going towards the end of November and no where with all the empty promises of phone calls and waiting for an assessor have I had a straight answer this is what we can do for you and get this finalized. I email them everyday but to this day I still have no answer on replacement or credit to my account or anything. My question is how long must I wait for something I paid so much for and no one is taking responsibility to help me?????
