Have you reported it through their support pages?  The one you're
after is probably:

Generally, checking is
the first place to go with GMail issues if you're not an Apps
customer; they have a link to reporting problems at the bottom.
Though if you're not an Apps customer (or can't find one to report the
issue on your behalf as not receiving e-mails from you), I wouldn't
hold out too much hope for a response from it.

Do let us know how you solve the problem in the end.
