AC Transit buses missing bicycle racks

[http://www.dummy.us.eu.org/robert]

AC Transit seems forever unresponsive to complaints about particular buses 
missing bicycle racks.  (The bus in question is bus #2504.  It looks like an 
older bus, but apparently did have a bicycle rack in the past due to evidence 
of bolt holes.  This particular bus is always full during commute hours; 
bringing the bicycle onto the bus is not an option.)

Is there any way to get AC Transit to either replace this route with another 
bus that does have a bicycle rack or install a bicycle rack onto this 
particular bus?  Sending e-mails only seems to result in apologies and no 
action.

Driving a car seems to be the only option now.
