I think this is more for verification of an account you've made or someone used your number for a registration to a particular website. I've received the same call offshore but I just missed it.
After that 1 missed call, they never called me again.
my ETH wallet has been stolen 1 year ago without knowing how the hacker got my PV key.
I changed the method of protection using 2FA so I am scaring if the hacker can pass 2FA
AFAIK, there's no association of calling with your 2FA codes. As long as you're the only one that can see it, you shouldn't feel threatened. 2FA is a good secondary layer for security so as long as you know what you browse, you'll be fine.
