Baf service with serta and sleep king

Good day , iv bought a bed from sleep king in phoenix and 2 months later there was something wrong as I slept on the bed 10 min I had serve pains and something was poking me I went in to sleep King to lay a complaint but thier service was disgusting as they only there to make a com , they said they will lay a complaint with the serta factory on 6 of June,no call back or feed back I called sleep King and they said it was reported 6 June I called serta facteoy and had joy then I called back 22 July almost a 6 to 7 weeks later nd spoke to some1 uncharged and he said he will try and sort it out which he picked up the same day and dropped of but they did not call to say what they was doing as it went to be accessed I call in myself to find out what was wrong the lady with an attitude said the shorten the stablerizer bar I told why you'll did call me to say you'll was doing that they said they didn't find no fault then why they shorten the bars they deliver it and I saw that the bed was not looking they way it went in but the driver said he only picks up and deliver. I slept on that night and though I was dreaming I was falling of the bed but got up in the morning to see my bed actually sunken on 1 side I called in but didn't get a call back Iv been a serta user for almost 40 years nd no Hassel this Tim I'm so unhappy I need them to send me a new bed and pick up this 1 as it's still under warranty otherwise I will take this up with my legal team
