My son recently told me that there is a new tactic out by these thieving scumbags. If you happen to answer and the person on the other end either coughs and apologizes or says, 'Can you hear me?' DO NOT SAY 'YES'!!! They will use your recorded reply and insert it into a scam recording and it will be used against you as an agreement for something you don't want! Pass this along. The 'bleeps' never sleep!!!  I just now got a second call asking, 'Can you hear me?' Caller ID said Long Beach, CA.
