> You sue them.

I'm a little confused here - you sue them, in small claims court, for not providing a service address?

How do you serve them without an address, for a claim of not providing an address?

I mean, I know what happens when I appear in court as the applicant/plaintiff, and tell the judge that the respondent/defendant was never served.

Okay, lets say the judge doesn't laugh my case out at that - how is my claim going to proceed? "I claim $X monies for not supplying me with their service address"?

(My understanding is that, by not providing a service address, all you can do is report them to specific bureaus, arbitration councils, etc. You cannot sue businesses, as far as I know, for not having or not providing a service address).
