You people should be smart enough to realize they all do it.
AT&T, Verizon, Sprint, T-Mobile. Which ever carrier you have I would bet they have dropped many people in the same way. Sometimes in business you do have to weed out the complete idiots. There is no way around it. How many times do you want to tell someone how to dial if they truly can not learn? I worked at a place we took this same stand, although only from the inside did we all know we were doing it. Just sent off some nice letter and got rid of the annoying customer.

Now having someone post the letter, that might not be so good and I would expect they claim it's fake.
