Sounds like the reps story makes sense but if thats the case then he needs to instruct his receptionist to be more honest. She shouldn't say they will call back when she knows it won't happen. All she would of had to do is say they will not be able to contact you by phone because of the show but if you would like a response faster just email. Then the guy would understand and not get impatiant. Its like droping my car off at the shop. You know thats its still in the same spot but they say we are still loking into it. Then you call back the next day and they say the same thing. Just tell me that you are swamped and will look at it next week so I can not have to worry about it.

Edit: I also forgot to add that it is good for the rep to come on and explain his products and why the slow response, kinda like a public apology. But when he says he knows the case and the proceeds to point the finger back at the costomer that was in bad taste. Any business man knows that no matter how wrong the costomer is you dont tell them, you just swallow and fix fast to make them happy and they will come back. My wife runs a daycar and we go through this all the time its just something you have to do (costomer service). but to take it a step further and go into the guys personal intrest areas like his personal web threads and point the finger at him I feel was uncalled for and shows the mentality of him and the company. Sure make the post and say why you could not get back fast to mend the fence for the guy and potential costomers, but its YOUR fault you were not staffed to go to the show, not the guys. Its YOUR fault your receptionist could not be honest and tell the guy "sorry sir your not getting any help for two weeksbecause..." I sure you left with instructions for her on how to answer the phone. If I was the guy and read this pesonal attack I would call the credit card company and tell them about an unauthorized transaction and then throw the cam awayeven ifit is fixed and go to his competitor for products.
