402-218-4566 calls no one talks

I received the call, answered it and a computerized voice said "Goodbye." ???

Exactly as tiffdeck said...I answered, a recorded voice said 'Goodbye.' and it hung up.

the 1 st time the (female ? )voice said fine goodbye. I have gotten a call from this # everyday for the past 3 days. I have called the # back @ least 7 x's because I have lots of family there . Every time I call the # I get a busy signal. I have talked to 6 different operators & none seem to beable to give any info on the #.

My husband called me at work and asked if I knew a 402-218-4566 phone number...nope.  He says that they never leave a message...and nothing happens.  We figure they are either soliciting something or have a wrong number.
