Sending messages to wrong person

I’m getting threatening SMS’s from these attorneys when I don’t have a Truworths account. See message below. A few days ago I got another message about my overdue Identity account - also don’t have an Identity account. They don’t address you as Mr/Ms So and So in their messages so I have no idea who their actual recipient is meant to be. They have got my number and send these messages yet no one calls to discuss the debt. Absolutely annoying! STOP THIS NONSENSE! I don’t know who owes who for the matter below but it’s not me. “Your overdue Truworths account has been handed over to Brooks & Luyt Attorneys for collections and the Debt Review Process has been terminated . An urgent payment of the full balance is required within 48 hours. Alternatively contact us on to make a suitable arrangement. Matter ***”
