MBD Harassment for Truworths

MBD Harassment for Truworths MBD keeps contacting me for payment of an Truworths account of a person i don't even Know!!!!! I have to tell them every time they call me that i'm not the person they are looking for nor do i no this person!!!!!! I'm being harassed by MBD and i'm at this point i'm going to open a case of Harassment against them as they seem to be so STUPID that they can't update there systems to take my number off there systems as i don't have any accounts by any stores and should stop messaging and calling me!!!!!!! They should be sent back to school to learn how to do there work correctly as in my opinion a grade 1 child is smarter than them!!!!!!!
