BAD SERVICE, FORCED INTO BUYING AND NOW HARRASSED FOR PAYMENT

So in 2015 I was unemployed, but prior to that I purchased some items from HOMECHOICE - I paid up my account as soon as I had the money. Thereafter, I was called on a daily , hourly, half hour basis by the HOMECHOICE call centres asking me to buy again, so the more I tell the agent, I am unemployed so I cannot afford any more purchases, I get another call within half an hour from the HOMECHOICE Call centre AGAIN. After I turned down purchasing bedding, i was called to make a loan, in the same manner, daily, hourly, half hourly, the more I said NO, the more they called, then I asked them to remove my details from their data base , but they kept calling, both for the bedding and the loan, I eventually decided that these people would not stop until I purchased something and against my telling them I was unemployed they kept calling, so I bought the blanket special, get 3 pay for 2, NOW they have debt collectors HARRASSING me for the payment after I told them that when I dont have the money to pay, you will harrass me for payment.. When I told them of the manner in which the sale was forced upon me and requested copies of call recordings, I was told but you chose to buy the goods irrespective, so, HOW TO DO NOW? because now I get threatened with LEGAL Action, GARNISHEE orders but when I refused to purchase I was HARRASSED with calls all the time to make the purchase and take the LOAN, so how does NCA, explain this dilema. I made a few payments on this account unwillingly , but I would still like the recordings of all the calls made to me several times a day, everyday, forcing me to buy something even though I refused.
