(313) 227-7300

This number has called me 7 times in 24 hours.  No voicemail and driving me crazy!  Must be a vendor sales person.....grrrrr...

This number always calls me...never leaves a voicemail...idk how they got my number.

I get calls from these guys almost every day - on my cell.I've tried to call back but I have had little luck getting through when I have time to call. They *never* leave a voicemail. Very annoying.

They keep calling me too, I called back twice. The second time, a woman stated..."I don't think we call out to home or cell phone numbers". She then asked to put me on hold, and ***g up on me.  Seems a little fishy to me. I registered my cell phone number with the 'National Do Not Call' registry, yet Compuware is the only company still calling my cell.To register with the 'Do Not Call' registry..visit www.donotcall.gov

calling 3 - 4 times a day. No message

The number came across, but no name. I let it go to voice mail. No message was left.

Also got multiple calls from Compuware, and received voicemail messages both times with a callback number.  This appears to be a generic Compuware number and the person on the other end will determine if you get any useful voicemail or not.  I s****ed receiving calls after downloading an evaluation of their product.

I have been receiving calls from this phone number at work. It s****ed after I went to a conference convention in FL where compuware had a booth at the expo. They gave away free t-shirts and had a free giveaway prize raffle on the second night. They collected our info for work in exc****e for the shirts/raffle tickets.

same as many of these comments - repeated calls after hours, no message.  like a test for active numbers.

Just got a call from them 5 minutes ago, and they DID leave a voicemail.  Caller identified herself as being from Compuware in Detroit.  calling to discuss "IT Service Management".

Got a call from them today.  No voicemail.

Here's that Compuware link with all the information you may need.http://www.compuware.com/contact/results.asp?zone=1&sp=California
