Daily SPAM calls

Constant unsolicited marketing calls from them and their "so called marketing companies" where I have been apparently removed from their list. In short, They can go and **** themselves. I am over their shirt and do not want any product or service their entire group of companies have to offer. It does not help to block their number as they change it each and every time they contact you. The only thing I want from them is information as to where they got my information from as I never gave any consent to any marketing company to contact me.
