Just called the second time today.  Did not answer the first one and sure as heck wouldn't answer the second one.  Do not answer unrecognized numbers.....PERIOD!

WARRANTY SCAM - DO NOT ANSWER
I answered and immediately recognized that it was a call center. The thickly-accented caller repeated where he was calling from 3x for me but I still couldn't understand. He then told me that he was calling about my 2010 Murano, which I leased in 2009 for 3 years and definitely don't have any more. It's one of those warranty scams.
