Miway harassing Sanlam Clients to take life Cover

I was given a complementary 3 month life cover from Miway as part of a Sanlam product I took last year. The 3 months finished a year ago now I am being Constantly bombarded by Call from Miway telling me that I MUst take a life cover with them as part of my Sanlam product. I refused and the sales consultant was rude to me. On two occasions now I have asked them to remove me from my database as I have spoken to Sanlam who have assured me that there is NO need for me to take the cover. Miway please STOP calling me
