…when they can still go ahead and place an order with you!?!
That makes no sense whatsoever.
This person showed all the signs of being a problem - asking for work outside of the scope of the gig, questioning extras and price, etc, etc, etc.
Most of us know that it’s not worth our time and trouble…so, I told them they would be better off finding someone else to do the work and blocked them. I’m fairly certain that the person would have been notified that they were unable to send any other messages!?
Doesn’t matter; 30 minutes later they place an order. And now I have to cancel.
