Harrassment and *****

These people have been calling me for over a year - I am not the person they are looking for - I tell them this every time - I tell them I have had my current mobile contract & number for nearly 20 years - they refuse to accept this answer & insist that MY nr belongs to a MRS X and that they have spoken to this person via this nr. Some weeks they call me each day - they have even gone as far as to claim they are phoning from Discovery. This is harrassment and ***** -
