I don´t mean to rag on you, but are you sure that you really worked at ISC? If you did you would know that letters to the Attorney General or to the Governor are useless. The company is located in Tijuana, Mexico, and I know this because I was an operator there almost three years ago.
What I really wanted to say is this: please don´t give people false hope. There is practically nothing they can do. If someone gets ripped off by ISC the only good thing they can do is take the discount they are offered and count themselves lucky.
Although, I read in this site of a customer who complained directly to the owner of ISC, Gregorio Galicot, and got a full refund. Galicot is also head of BBG Communications.
Another suggestion, if anybody wants to be done with the whole thing as quick as possible, is to not settle for the 30% "adjustment", but keep on them until they agree to take 50% off.
