Homechoice bad service

I have an account that i have been paying every month since disbur*****t. Now i have a balance of plus minus R600 and have sent 2 emails and tried to call homechoice for a settlement letter as i wanted to close the account last month. I sent the emails on 25th March 2019 and instead of the letter all am getting is sales emails and calls. This is not the first time homechoice does this to me, i regret why i even bought from them after my first bad experience with them. Homechoice used to call me everyday sometimes even more than 10 times a day. One day they called me at 10:58 in the evening to sell me duvet covers. The service at homechoice is bad, all they know is to call you numerous times a day when they want you to buy but when you need their assistance they are never there.
