Disappointed

I purchased a bed less than a year ago for my guest room, so not used every day, but i do have guests fairly often. It started to wobble and I have tried to get it sorted out, but having a hard time getting people to return my calls and eventually when they sent a team out, they got to me after the appointed time so I was not at home, now they want to charge me a callout fee. Not impressed with after sale service.
