Can a faster business send messages Aauto users in the background?

A faster businessman can send private messages by telephone. If what we bought in a small shop is not particularly pleasant to hear, if we want to type after sale, we will have your after-sales phone number first. It is ok to call your after-sales phone number, so that you can make it clear that I once bought a dress and was not very satisfied, so I called him after-sales.
