*********** and annoying business

This company is doing collection and I told them it's a wrong person and they harrassing me. Tried blocking them but their irritating emails come through still. I don't even know how they got my details because they said they're debt collecting on behalf of Truworths and I buy nothing from there.

This is really irritating and I need them to tell me how they got my details and stop looking for wrong person on my email. There's not even verification to get correct details. They're looking for Ms SB Kelefetswe and I'm Mr SE Kelefetswe and I don't know that person
