Issue routing to ATT AS7018

Looking for anyone from AT&T who can help me out. I have an external router sitting on an ATT owned /30 subnet in NYC....seems the only advertisement for this subnet to any of ATT peer is a /9 aggregate out of Miami. Causing huge latency in our internet path. Support and account team has not been able to help me. I'm expecting a more regional aggregate to be advertised so we're not adding 35+ ms to our path. Maybe that's not reasonable or doable? if that's the case, I'd like to know why? Let me know, and I'll contact you off list and provide more info. Thanks in advance!
