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.
