Got two calls today from this number. Left no voicemail message.

Got a lot of calls from this number.  It is OnStar, and if you call back there is an option to remove your name from their call list.  I believe they were calling to tell us of a mistake in our account, which I corrected on-line.

I keep getting calls from this number and when I answer there is no-one there.  I found out it is OnStar and had my number removed. You would think if they're going to call they would at least speak to you. I get several calls a night from them. I don't know why it will take 10 business days to get off the list either. I get 10 more days of hell. Thanks OnStar

I received several calls a day from this number & finally received a message on our answering machine.  It is OnStar calling to welcome us to OnStar and congratulate us on the purchase of our new vehicle...which was a surprise since we haven't purchased a new car, let alone one equipped with OnStar services.  Not sure how they got our number, but I did call the number back and ask them to remove our number from their calling list.

I called the number and was given an automated option to remove my number.  I entered my number and was given an automated response my number would be removed.  If I want additional Onstar services I will initiate the request.  

OnStar's legal counsel is Joanne Finnorn.  Call their corporate offices & threaten them as I did & your number will be removed.

Just got a call from 1-800-638-5828.  No one on the line.  To teach them a lesson, I haven't hung up my phone yet - they have been paying for 1 hour 44 minutes so far of long distance call to Canada.  Even if they pay only 1 cent a minute, I don't need my land line so I'm not ready to hang up for a long time.

I got two calls from them at work today...didn't anwswer them because
I am too busy with Iraq right now.

Getting numerous calls with nobody at the other end. Sometimes one right after another.Seems intentional and abusive.

Got 2 calls one right after another with nobody on the line from telephone number 1-800-638-5828. From reading this page i guess it's OnStar call spamming. OnStar sucks!

Got two calls from them today.  Answered the first time, noone was there.  Second time, let it ring, they didnt leave a message.

Got a call from this number. Carla with Onstar. Said my credit card was invalid. Also said I needed to update credit card information. I called Onstar and they said the number (mine) that was called is not in their system. Totally confused. Either Onstar is totally messed up or their database has been compromised. Either way, it's very scary!

Got hang up call from that number today.  Called it back and got an automated message to call a different number at a charge of $5.95.

I receive calls from this number daily.  No one is ever on the line when you answer it and then they almost always call right back.  I called it back and only got an answering service.  I requested to have my number removed.  We'll see what happens!!!!
