These phone calls are extremely annoying, calling about "car warranty" which we have repeatedly said "we do not want"! It doesn't matter if you block them, they will just call from another bogus noumber.
I answered to silence on the other end and then hung up. ID says "Binghamton, NY". Possibly related Binghamton call later that I didn't answer & no voicemail from 607-203-9232 about 2 hours later.
