Phone everyday with different numbers

A nurse at a hospital used my mom's number as a patient and mine as an emergency contact as referrals probably to get a free gift. That is ******* to do that and highly unprofessional. It also does not mean that we have given consent for platinum life to phone us. As a very old policy holder who had to cancel due to constant harrassment I'm well aware how this company and their phone calls work. Due to the POPI act companies cannot cold call potential clients anymore for business. I work in healthcare as well and I can't answer these irritating non stop calls. Please revise this referral system as people use this as a joke these days
