Who called from 2400000000

I recieced calls from this number identifying themselves as 'card services'. Whenvwe asked that they not call back he began hitting on us and calling back to continue hitting on us. Don't give these scammers a minute of your time, just report them

Rude and hit on me too.

They called and when asked them not to call me anymore because I have no buiseness with them
they said that they will cancell my credit card. I asked which one? All of them they said.
