Gross Harassment!

Truworths has been harassing my mother since last year. She receives phonecalls everyday, all day from people claiming that she has arrears when she infact does not. No one at any of the Truworths branches around Gqeberha has been able to help her, it's like they're hiding something. She no longer has an account with Truworths but they still continue to call her, what's even worse is that they even call me, my question is...where on earth did they get my contact details!? Truworths needs to review their association with their debt collecting companies, what they are doing is disgusting.
