Contacting me without my authorisation

Dear MFC,<br> <br> Please stop giving out my contact information to other companies. I have explicitly marked the block stating that you are not allowed to contact me or share my contact information for marketing purposes. <br> <br> Also, contact the people and companies and affiliates to whom you have already given the information and tell them to stop contacting me.<br> <br> If this is not remedied I shall take further steps.<br> <br> Regards.
