I called that distributor and asked my rep to go to bat for you. The problem was apparently caused by your rep dropping the ball. Then, by the time you called to ask where your stuff was, the manufacturer had raised their prices. The problem was the rep's fault though. She should have furnished the products to you at the quoted price.
My rep agreed with your position on this. He'd take your account on himself but he's limited to major accounts. Instead he's calling the regional manager to ask that the matter be resolved *and* that they assign a different agent to your account.
I expect you'll probably get a call from them. I'd encourage you to give them one more shot, especially since there pricing is so aggressive.
