Initial call was from an appointment setter. Sounded interesting so I let him schedule an appointment for an online demo with a sales rep a few days later. They rep called as planned but I had changed my mind so i let the rep know that immediately. The rep was courteous and said he understood and would follow up with me in the future.
The original appointment setter called me 3 times since my cancelation of teh demo wanting to know why I changed my mind and said that he would not have wasted someone elses time like I did.
