Signpost review: they were too pushy

I thought about the app, which offered the company www.signpost.com. I tried their demo version and understood that it wasn’t for me. I replied to the agents that it wasn’t what I needed. But the rep told me that I need to try it blah-blah. I told “no” and asked him not to bother me. But they continued to send emails and called couple of times. It was so annoying and persistent that I thought about changing the email address. Awful company.
