Harassed by unending phone calls from different numbers

I am being harassed with calls from Platinum Life, because I have apparently been nominated by someone called 'Glodina' to receive a free gift. I have no friends or family called Glodina, and if this is someone who has my number from a business transaction their behaviour is ********* and *******. I have blocked more than 15 numbers on Truecaller from Platinum Life. I am not interested in receiving calls from you. Surely you get the message when your numbers are unanswered and blocked? I feel harassed, and as such I will never use your company as it has left such a bad impression on me. Please stop calling me, and ensure that my number is on your blocked list.
