I'm sure this is true for a lot of companies, many have a support department that takes care of the "difficult cases". On of the quickest ways to get in touch with them is through sending emails or letters to the CEO. Bonus points if strongly worded, although the people working there will hate you while trying to help you out. They might be better connected and have options to handle things that a normal support person doesn't have.
