Harassing me without permission on a weekly basis

Hi <br> Momentum had been phoning me each week wanting to sell me life insurance. This despite me being already a client!!! My number is also registered on the do not contact list which makes it ******* to cold call.<br> I have asked them to please remove my details from their data base and please stop harassing me but to no avail. Guess I would need to cancel all my products with Momentum and open a case against them for invasion of privacy and harassment.<br> Seriously! I am so put off Momentum now!
