Received to calls on my cell phone from this number. They don't leave message. If you call the number from another phone it says that it is not a valid number, but when I redialed from my cell it went through and a recording gave me the option to get off their list.
I have been receiving calls on my work cell phone from this number almost every other day since 11/22/2013. I answered it twice and no one responded on the line. Most recently the calls are nearly everyday at different times, and there is never a message. What is the purpose? Do telemarketers get paid based on the number of calls made even if no one answers?
