What should I do if my condominium manager can't register me for TM30 within 24 hours?

So I have done my visa run and got my education visa no problem.

When I got back to my condo in Thailand I asked the condominium manager to register me as back within 24 hours because of the tm30 process.

She said she cannot do it until Monday as the office is closed. I have checked and she is right.

She refuses to do it online saying she doesn't have a username and password. I told her to register or get the owner to register and pass her the details but she said its not possible.

So my question is how can they enforce a strict 24hr registration when they close at weekends.

Is there anything more I can do to help her?

It's probably going to be another fine.

Is there anyway of reporting the apartment owner or manager if/when they refuse to do it as per the tm30 rules?

Sorry for the long post.
