Damaged goods cant get a cancellation

hi i bought a lounge suit in December they delivered them on a Saturday, immediately on that day i went back to report the damaged goods as i was not there when they delivered they promised me to come on a Monday whch neva happened , i kept on goin to the store daily and they would call the warehouse, so i decided to cancel them because i couldnt use the other two chairs becz of the broken legs, The manager asked if she could giv me a micro-oven or a home theatr and not cancel i ddnt agree as my fiance and i had alredy made a decision, they came to colect the chairs and they told me the warehouse ddnt want to acept them because they were dirty. the store asked me 2go and clean them, i hired a prestige company to go to the warehouse and cleaned that lounge suit which ws only one chair that had to be cleaned, sinc after that i have been recieving a cals regarding payments and now everytime i go to the store its either they are ofline or thy say thy are busy they will cal me which they never do, even at the warehouse they told me its for the first time since they hav existed seeing a client coming to wash or repair their returned goods,im very disturb al i need is a cancelation letter
