Incorrect Information and HARASSMENT!

I have constantly been receiving calls from ********** 000 Norman Bisset and Associates. Every time I received a call I have told them to remove my number as this does not belong to the person they are looking for, but the lady I speak to is rude and arrogant and keeps questioning me. This has become very frustrating as Norman Bisset should be doing research before harassing people. There is a reason cellphone numbers are registered. I am tempted to take this further as the person who keeps harassing me is rude and very abrupt. REMOVE MY NUMBER FROM YOUR SYSTEM!
