Who called from 3475022527

Caller ID displayed number with "Client Services" as identifier.  May be a Bayside (Queens), NY number.

I recieved a call from this number; when I answered, there was no sound & then the call was lost from their end.

this # called me too, but i wasnt there to answer, so idk what would have happend if i did answer.

This number calls twice a day, and if I answer there is no response.
How do I get them to stop calling?
