complain

I bought a bed in December 2014 and when it was delivered we found that there is a plank broken. We took a photo with a delivery guy and wrote a letter complaining. January they sent a technician to fix the problem but he failed and he wrote a letter to his bosses recommending that the bed be taken back to the factory. In much the bed was taken to be fixed and in April they brought it back with much more trouble than before, the delivery guy suggested that it taken back to factory for fixing and up to now I haven't received my bed. And Im fed up need my money back. Please help
