Rude Home Choice Consultants

I'm so ****ed and angry with Home Choice their consultants are so rude. I had an account with Home Choice and l paid up my account before the given time, and l don't owe them anything. Now they calling me asking me to buy from them and l tell them that l am currently unemployed, and l have requested that they must not call me anymore but they keep on calling and being so rude. When l explain to the guy who called today, he's a Xhosa speaking male he's was very and rep**** by saying "Awuzange uxhelele mna lonto" what am l suppose to do must l call all home Choice consultants and ask them not to call me?. Cause whenever they call l them one and the same thing. Unfortunately l couldn't get the consultants name but will attach the number they called me with.Please Home Choice block my numbers l don't wanna recieve any calls from your rude consultants cause l keep on blocking their numbers but they always come with different numbers.
