Hey dumb [***] who cares if they called you are not, the purpose of this site is to tell people who is calling!!! Not that someone called you are not so next time try a little harder.
Calling 2028034939 back only gives an option to opt out of future calls; they do not identify what company they are calling from. Personally I ignore the opt out as I assume it's just a bot collecting valid telephone numbers to sell to cold callers..
