I'm a small family owned business. No matter how many times I said NO, they called and called and called! Especially in the middle of the day. I called them and asked them to please remove me from their list because after asking again for them to stop, they hung up on me. Wow, now those are services I can do without. They called not once, but 3 times and hung up! Make your own decision, but don't you think their time is better spent soliciting and servicing people who want and need them.
Pros: Have no idea, but would not take NO for answer!
Cons: Wouldn't even consider finding out.
