To be honest I haven't had much success it convincing a tier 1 to modify someone else's routes on my behalf for 
whatever reason.  I also have had limited success in getting them to do anything quickly.  I'd first look to modify 
your advertisements as much as possible to mitigate the issue and then work with the other guys upstreams second.
