Pham & Dhaka Attorneys - you are contacting the wrong person

Bham & Dhaka have been contacting me for the past 4 months in relation to a person's estate who I have no relation to, do not know. I have on every call made to my mobile indicated that they have the incorrect contact details. They have continued to contact me. Today they sent an email - this is an absolute joke that a legal firm cannot understand when someone tells them they have the incorrect contact details. I find the fact that they say they will remove my details, yet continue to call and now email to be unacceptable.
