Chasing sales people

I don't quite understand why people whose only job is to generate new business have to be chased by their prospects to close a deal. I have dealt with several companies now to rarely find people who are able to hold a middle ground. Follow-up without being pushy, but don't drop the ball altogether!

A company we want(ed) to do business with. We called them up. Met with them. Discussed what we wanted in detail. Exchanged emails. Met again. Then, the person in charge went on 'vacation'. That person did not bother to hand-over pending issues, it was just left. I called. Nothing. Called again, found someone else. I asked them to take over.

Then it was just a continuous hassle of trying to get them to send me a lousy proposal. I reply within 3 minutes of receipt. He can come up with 3 excuses for not being able to do something he said he would do.

Then you have the super-eager salesman. He's here today. He'll be here tomorrow. He's got 2 proposals in hand, in case you don't want one or the other. Just a tad too pushy though. You don't feel comfortable dealing with him anymore. He's always in your reception area waiting for you (or someone).

Everything in moderation. Even sales!
