WEEKLY CALLED BY DISCOVERY LIFE FOR FINANCIAL SERVICES MARKETING 2017

Dear Sir or Madam, I am called at least 3 times a week by Discovery Life since 2017 trying to market financial services to me. Sometimes I would be called 3 or 4 times during the same day. As a businessman I receive numerous client calls and answer and return all my calls apart from SPAM calls as per true caller. I have constantly asked to be removed from the Discovery database as I am NOT AT ALL interested in any of the services their group offer. I have asked nicely and consistently to be removed from their database. Only a day or two later I am again called !! I am really at the end of my tether and are trying to establish where to report the company and if necessary take legal action. Is there any way to deal with this issue effectively and straight away? As a consumer I believe in having the right of choice who to engage with in business and for my personal affairs. In my view this is serious infringement of my individual rights.
