Half the problem here is too many emails. If you had just phoned the dude, got your disappointment of your chest etc, most of this could have been avoided, I reckon. Email leads to entrenched positions which then become impossible to move on from.
It might not be "right", but sometimes being happy is more important, it might yet be salvageable, if you ring him up and talk it through, unless you have already recovered the frame, obviously.
With respect, this is rubbish.
I used to import a lot of high end musical gear and often to order. I was working full time at the same time, and answering emails was far preferable because I could do it in my downtime.
Phone calls pull you away from whatever you are busy with.
What is unforgivable here is the lack of communication from the service provider, and I reckon he should change his ways and stick to stated time frames in future.
If he is not making enough money to up his game, get out of the game.
The doctor diagnosed me with hereditary diarrhoea. I can't understand, I wear a kilt.
