Homechoice=poor service

Good day. In April 2015 I bought 2 duvet sets from Homechoice . My husband received the box and didn't open it. I came home around 5pm and opened the box. It only contained 1 duvet set. I phoned homechoice the next day and was told that they would look into the matter and get back to me. They never contacted me regarding the matter again-I had to contact them every time and was told they will get back to me. Later in 2015 I was told to complete a declaration form stating that I didn't receive the duvet as well as send an affidavit. Thus I did. I went to Homechoice personally early in December and was told they would get back to me. This never happened. Now they handed me over to MBA credit solutions for debt collection (queries@mbd. co.za). Can you please assist me with this matter. My account number ***. ID number: ***
