Medicare bot calls

I am being bombarded by Bot calls. its mainly woman's voice. she comes on like "oh, hey there. can you hear me? has anyone told you about the Medicare program food allowance? its going to end soon so I want to see if you qualify. are you on Medicare part a or b?.. answer.. no.... well its ok i can see if you qualify for this other program.. are you over 65?.. answer. no.. . cluck.. hangs up. when I block the number, it calls from another number.. generated from my same area code. I get 10-20 calls a day
