Got a call today from 978-223-9672. A woman with a very heavy accent (maybe Indian) told me she was calling from the "Vehicle Registration Department". Told her I could not understand her; she hung up.
Same thing happened to me. Couldn't understand a word she was saying until she said the make of my car. It could have been an extended warranty program (or scam) or something like that. I just hung up. If it calls again, I'll block it at sprints website.
