It does seem odd that the call appears to come out of the blue, but sometimes it does.
Cold callers are only doing their job, so I do cut them some slack. However, those that don't listen and continue to waffle on won't get any sympathy from me. It's rare for me to be rude to them, but sometimes a simple thank you and goodbye, and to immediately hang up is the only way to end the call.
