There is but one constant in the universe: No matter how many times via phone, in person, or over email that you tell a sales person that you will get back in touch with them once you hear something… Whether, yes we will buy your product, or no we will not… Especially when it is not up to you to make a decision, but your boss for whom you've done the research for, turned over the information and are waiting to hear back from… The sales person will incessantly call and or email you every 2-3 days non-stop to "just check in" with "how things are going". Constantly. UHG.
