6 calls today, 5 yesterday and I can't remember how many the day before. I called from a landline 3 times, two times got a busy signal, the third time it sounded like a fax machine, but not quite. more like R2D2.
This number calls me nonstop up to 8 pm daily. I FINALLY spoke to someone from this number just a few mins ago. The number is from a research company that helps you find grants for business, or school! Don't even know when I had signed up and to be honest I don't think I did. She was polite and I asked her to remove my number from her list. Hope this helps :0)
Oh and BTW you have to wait about 5 seconds before you speak and get a connection. Don't hang up too fast, you need to let them know that you DO NOT want anymore calls!
