MBD **** Along with TRUWORTHS

I have been receiving calls every day from MBD notifying me that Ms CS Dlamini has an outstanding Truworths Account and needs to be paid. Firstly I don't have an account with Truworths. I don't do Credit period. Secondly, I received a Truworths card in my mail as well. How do you have my details? Or it seems like someone open an account with my details.
