Yeah, I've had this more or less happen to me.

A telemarketer from the bank I used to be with called me on the day of my brother's funeral to try and sell me life insurance.

Terribly bad timing as at the time I was waiting for the car to pick my mother and myself up to lay him to rest.

I'd like to say I handled it well, but I didn't. I vaguely recall some hefty swearing on my part the next day as I closed my account with them.
