     I didn't contact them.  I'm disgusted with them after seeing how
they cheated my faculty advisor and, when I asked them to rectify
their errors, they refused to do so.  I recommended to my advisor that
he turn the whole matter over to the university's legal counsel.  He
told me that he was not going to renew the service contract any more,
so I doubt he will bother with having the legal counsel deal with it,
but either way it will be his decision and it's now out of my hands.
Given their denial of service while we had a service contract, I doubt
they would do any better now that we no longer have a service contract.
