Ask HN: Anyone know anyone over at T-Mobile corp web operations?

It appears that account.t-mobile.com blackholes requests from our stupid-small network (AS21743). So I can't complete my "T-Mobile for Business" registration 'cause they're 408-ing all requests from our AS. I live in Seattle, so my condo is blanketed with Starbucks Wi-Fi dialtone, and T-Mob hasn't black-holed their net provider. So I'm able to complete my task. But I just wanted to see if I could get ahold of anyone at t-mob who a) knows what an ASN is and how it relates to anycast and b) can tweak their blackhole list so users of our tiny Seattle-based WISP can access their services. Obviously the phone support guys don't know what's going on and sadly, our WISP slept through the NANOG meetings so doesn't have any contacts.
