Well, this was a first for me. One of my buyers received their order and then immediately called me on my cell rather than using the Amazon message system. This was the same day, only a few hours after the package was delivered to their address. But they didn't call about the order, they apparently just wanted to chat with me. I didn't pick up the call, because I did not recognize the number. Based on the buyer's identity (I of course googled them; they have a religious title) and the content of the voicemail they left for me, I think they are interested in proselytizing me. I did not call them back, and am not sure how to handle this. Sellers, Amazon people --- what should I do here? Ignore them, write them a message? If I ignore them and they leave me a negative review because of that, do I have any recourse?
