mattress 1 one inventive tactics: ignore everyone Hollywood Florida

On Sept 6, I bought a mattress, boxspring, and mattress pad from Mattress 1 One in Hollywood, Florida.  They were to be delivered on 9/9/14 in the evening.  The delivery people came with the mattress and pad, no boxspring.  They called the shop.  The delivery men assured me that the boxspring would be delivered between 2 and 6 on Wed, 9/10/14.  I work and asked a friend to sit in for me.  No show.  I called the shop and told them that I could not do one more four hour time slot, and I needed the boxspring delivered the next day after 7 when I got home from work.  They said fine.  Again, no show.  I called the shop again.  They said that the boxspring was out of stock and should be refilled soon, maybe Monday?  I asked if they had sold me an item that they did not have and got a noncommital answer.  Meanwhile, I am 64 and sleeping on a mattress on the floor.  I can barely get up in the morning.  The whole idea of a new mattress was to make my life better, not more miserable.  I asked them to have the manager call me on Friday, 9/12/14.  The gent said he would.  When I was getting out of work on Friday at about 4:30, I had not yet received a phone call.  I called the shop and was given a direct line, supposedly.  I called.  The voice mail box was full, maybe with other complaints for all I know.  Now, I am going to get a  new set this weekend from someone who can deliver me an entire set.  I am not asking for much here.    All I want is for them to pick up the old mattress and refund my money.  But no one will talk to me.  I will have to go to the store tomorrow and kick up a fuss, I guess.  What an effective way to deal with people:  give them a number that doesn't work and say there is nothing I can do.  I am done.
