Who called from 6064335800

this is sprint customer care

Did not recognize the number and could not understand the message.  When I attempted to return the call the message was this number is disconnected.

Recieved a call from this number today asking me to pay a sprint bill for a friend in another state. The amount was 3x what I was told that it was. Said she was on a conference call with the account holder at the time. When I talked with the account holder later they said they were not on a call and heard nothing of the conversation. Called the number back and it was disconnected. Beware before you send any money!!!
