The moment I asked who was speaking, I get a snide voice asking who is speaking. Then when I replied "I think you have the wrong number" I am accused of calling them back after answering when they clearly called me first. When I tried to clarify, they respond with "I get a fat c- on the phone." Just insulting and flat-out rude. A simple apology would have sufficed instead of blasting an innocent person answering an unknown mobile that could have been anything from a private service to a scam.
