Everyone is busy, and everyone wants it now, etc...
Truth is, you can be nice and wait if talking to the managers/store owners don't work...
If they can't give you a date, then you are going to end up having nothing but issues with this place and most liekely that will never fix the machine right. Generally bad management, bad service all the way around.
And yes, if you go over their heads, they are liable to not to be nice to you from now on and you will have to travel to another place to get your equipment worked on.
But you just spent big money for a machine that you don't even have anymore. I wouldn't even accept it back. If the time frame is in your favor, I would tell them give you a new machine, or you want your money back. If it starts out with issues, it will probably continue to be an issue is some form. Who know what will get screwed up fixing the problem.
Don't wait around on this. Try the diplomatic approach first, I always find the deals to be in my favor when I do. If that doesn't work then get agressive quick, and if you have to fight to get your money back and go somewhere else. You don't have to me a jerk, but don't take their BS either.
I have other suggestions if the above doesn't work, but I will keep those to myself as I don't want anyone getting into trouble.:laughing:
