Very Bad service by the store manager

My Father in law bought a bed at Best Electric at Dobsonville mall around end February.By march the bed collapsed he then called the store they asked him to send pictures of the bed he then sent the pictures to the sales person who was helping him when he was purchasing the bed,then the lady couldn't help him.End of may he went to the store only to find out the person who was helping him nolonger works there.He was then told by the manager that thy will not be able to help him as the assistant is nolonger working at the store.He is now stucked with a collapsed bed paying it and no one is willing to help he was told that it is his problem.
