it must explain it, messaging to several sellers, someone from China spammed them with responses and they now ask me to verify something on Friday night LOLOh wow. They probably signed up for text alerts and now are alarmed that they are getting your messages as texts. Ummmm. Maybe they sent messages to several sellers and think all of the responses/texts are coming from you. That doesn't explain why they are so confused and upset about it though! Some people are so clueless that I wonder how they can get through a single day alive.
I will feel uneasy to sell something to such a "confused" buyer, I'd rather cancel sale.
