Prank/dropped call

Good day I am feeling very uneasy and harassed by the above company. I have been getting calls for about 2months now from Affinity Health. When I answer they drop the call. I don’t understand why, I have never signed up with them or enquired about the service. I only found out about them because I searched the number in True calller. Telemarketing is already irritating as it is, I answer out of courtesy and now have the calls dropped every time. This is not on, please may you remove me from your data base, I am highly annoyed, my privacy and peace is being violated at least once a day. Your prompt response will be highly appreciated.
