Stop calling me

Creative Space Media have been calling my personal mobile phone for the last 5 years, hounding me to enter the MTN App of the Year awards. I haven't worked in the app space for many years and each time I request that they remove my number from their database, yet they continue to call me. Not once or twice but over and over. I'm not even sure this is legal anymore given POPIA is now here. Team at Creative Space Media if you get this, PLEASE remove me from your database! I am tired of being ignored by your team.
