I get it and understand why you're annoyed, but I hope you'll give him or her the benefit of the doubt. Some people are simply more aggressive than others but sometimes deals get stalled or you get "ghosted" as a vendor... which means there's just no response for a period of time. As you know in sales, you're reporting to a boss who asks you (quite frequently sometimes) about the status. Perhaps this person just needed a response, whether it be "reach back out to me next month. I have more pressing matters" or "this has been put on hold for a while." This gives them the info for their reporting and allows them to ask if they can follow up with you at a later date. It all comes down to communication which is key in any relationship personal or otherwise. In sales, there's nothing worse than respectfully sitting in the holding pattern of a decision to find out that your prospect has gone with a competitor. It can be a bitter pill to swallow
