You should direct the question to whereever you are a customer.

These things usually happen when one party doesn't want to peer with 
another party and the one that wants to peer, will route traffic really 
far away to make sure that both parties are paying for the traffic, thus 
increasing the motivation for the other party to change their mind 
regarding peering.
