As this is posted in the General forum, I assume that a non-sales person can express an opinion. I am a non sales person and maybe, or maybe not, some of the sales people posting hear might be interested in a little feedback from people who buy services.
This was a polite and short call and I wish all sales calls were like this. In fact if I received such a call I might actually not have said "no thanks" and might have been genuinely interested what this person had to say. Why? Because there was no hint of a hard sell to follow.
With the usual sales call I get, you can tell that the hard sell is coming within a split second and you will know that the experience is not going to be good. They will try to be over-polite. They will be over familiar ("hello how are you today"). They will make untruthful claims ("someone will be in the area tomorrow" ). They will not let you interject. They might be polite, but very controlling and focus on themselves rather than listening to you. Some try to focus on you, but the focus is usually by asking intrusive and commercially confidential questions such as who your present supplier is etc.
Just a few thoughts.
