Constant Harrassment

I opened a homechoice account in 2016 closed it in 2017, somewhere along the line someone by the name of Miss Kwena used or mistakenly was allocated my number, i been getting calls asking for this specific call center since 2016 till to date, even if you shout at these agents that i dont flippen know who the **** that person is and they must stop calling my number. I am irritated get your call center in order. i dont want harrasment in 2018, please.
