I received the same sort of calls from this number at my work, I tell them to take us off their list and they hang up on me and say they will call back!

She calls me and after complaining about the the voice quality asks my name!!! I say why? you have called and asking my name? she hangs up!!!

There is something special about this number from this telemarketer. My IPhone was on Do Not Disturb setting but it still went through. When I tried to call back, the number doesn't accept incoming calls.
