Had received an exact same call before, from a different number.  Seemed (if I recall correctly) on that other instance, the girl (the caller) says "Hello?  Hello?"  as if she has a wrong number or can't hear anyone ... and then proceeds into a promo sales message.

Well, THIS call starts out in the identical way, same voice, same inflection.  

I just clicked Delete and hung up before she could proceed and waste my phone units.
