DO NOT follow this advice. DO NOT call the number back. Do not take, or return, calls from numbers you do not know. NEVER give out personal information on the phone. You have no idea who you are really talking to, or where in the world this call will take you.

Just call back the number and push 1 and you will be taken off their call list.

what are you doing when these calls come through?

what time of day is it?

Call me crazy.  I think these calls are a notice that someone is taking notice of my actions.  If I recall, I get these calls once a month when I fill a certain medication.  I get the call five minutes after I have come in my door.  It is a hunch.

Get a hobby!

Have received numerous calls from this  number and no one ever responds when I answer.

309 948 6639 called several times no message don't know who it is-we don't use Vista natural gas so I don't know why they'd be bothering us IF it is that business.

tired of these calls-the only thing the answer machine gave was it was from Rock Island IL .

Same thing here, twice today

they are just slow to answer, like an automated system does the calling then they pick up after  you answer.  Its Vista natural gas.  Nicor gives them your phone number and it's just to get you to have them as your supplier, but Nicor does everything else, like the billing, customer service, meter reading, etc.  10% first 2 months, then goes to variable rate that will supposedly be lower than nicor, but it comes with a $2.99 monthly account maintenance fee.

SCAM CALL. No one ever says anything when I pick up.

Same thing happened to me on July 5, 2012.

Call with no one at the other end.  Called back.  Call did not go thru.....wondering if a scam?
