Platinum Life harrasment

Platinum life has been harassing me on a daily basis since November. I have declined the "free" gift when they asked me my address, where do I work, what is my work telephone number, what is my position at work, how much do I get paid, they then proceeded to ask my ID number, where I bank and what type of account I have. I have been blocking their numbers but they keep on phoning me from different numbers. I would really like it to stop. I know I have been nominated by a friend, I know you want to send me a free gift and no I do not want the free gift. I know you are a authorised financial services provider and no I am not giving you my banking details, ID number etc and yes I know you want my details so you can send me tips on how to "bank better" the first tip should be not to give out your banking details on a phone. Please add me to your do not contact list.
