They call several times a day and never leave a message.  Often as early as 9:00 AM and 8:45 PM.

I recived 6 calls from this phone number TODAY!!!!!!!!!!! Between 9 am and 5pm.  I just called the company that was listed above and when they answered they said it was AIG insurance.  After explaining the problem they said they would place me on a Do Not Call list.  I told them I was on the national one and the customer service rep said sometimes they can get around it due to credit cards you own.  I think they may be trying to reach the person who owned the number before us, as I know he had Homecomings Morgage.  

STOP CALLING US....THREE TIMES A DAY FOR THE PAST THREE MONTHS!

same as others report -- lots of calls, no one there when I answer.  Based on the information and research from fellow sufferers, above, I went to the GMAC website and sent an email to customer service, asking them to notify their departments [we have mortgages with both GMAC and Homecomings, their subsidiary] and whoever they "sold" our number to, telling them about our DoNotCall status, and offering to tell the world, the state AG and BBB about their unethical behavior [#1 calling w/o permission, #2 not answering when I do, and #3 requiring me to call them "at their convenience (when they're open)" to discuss it.]

We have received several calls from Global.  If you are on the do not call registry, go to their website www.donotcall.com and file a complaint.  If you're not registered, go to the website and register your number.
