Very bad service from homechoice

Hi I am Fikile Dlamini, Last yr december I bought a bed from homechoice , a week later the bed was delivered but the mattress was damaged on the sides. I called them to inform of the damages. I was asked to send pictures via an email which I did. The next step they collected the bed via their courier company. I then asked them to cancel the order since I didn't receive what I wanted. Since February I have recieving calls from them asking me to pay for something I dont have. Everyday I have to explain my story to someone from their call center . They always have the same response "sorry Mam will fix our error" but for the past 3 months I have been receiving calls from them about this payment about a bed I dont have.
