Unable to submit IP Infringement Report Form

[lkm01]

I have spent 2 days trying to report IP infringements using the online form but the completed form will not submit.  
I have tried a different device, a different browser, checked my browser is up to date, an incognito browser and nothing works!  I need to deal with this urgently so any advice would be appreciated.
I have emailed the legal email address but had no reply or acknowledgement of my submission.
