Contract negotiations advice?

I am dealing with a large telecom which purchased the small telecom I signed a contract with. Despite signing only 1 contract with them, the two racks, and the bandwidth which feeds 1 rack (I connect privately to the second rack at no charge) all have different termination dates. How signing one contract resulted in 3 different end of term dates, months apart, I can't quite figure out. Can anyone point me to a mailing list or discussion forum containing advice on dealing with such issues? And the wider issue of negotiating good rates with telecoms?
