But I would be glad to solicit "similarly situated customers" which is code word to a legal department.
Nice. I do tend to find that when a company is giving you the cold shoulder or generally just being arrogant a tactical letter to the legal department and/or one that just uses legal terminology tends to do wonders. Often these shady companies seem to forget that the law and terms of contracts apply just as much to them as it does to the customer.
Simply pointing out that you know they're in the wrong, have evidence to prove it and will actively seek damages if they don't sort themselves out is often all it takes to get some of these annoying issues resolved.
I once had a friend that was getting pushed around by a shady property management agency for his apartment. I sat down with him and went through his lease and we documented every tiny little thing that this agency had done in violation of his lease (e.g. sending construction workers around outside the hours agreed to in the lease).
I helped him write a letter that was basically a notificiation of intent to pursue damages for breach of contract. Boy did their attitude change quickly (perhaps due to the fact that a bit of background research showed that they had recently been successfully sued in small claims court by previous tenants for similar issues).
I guess the take home lesson is to just keep a cool head, but don't be afraid to aggressively pursue and defend your own rights.
