Carmen from cardholder services called using a new number.  The good news is that I will now block this number. The bad news is that the telemarketer will, in no time, find another one to use.  I wish there was a cost to such callers to discourage them from calling numbers that have never answered their calls.  But I guess the cost to them is so low that it is not even worth trying to weed out numbers that are never productive for them.
