How can I obtain a valid email address for the Police Clearance Centre in Chiang Mai, Thailand?

Hello 🙂 back in April, I did the Police Clearance process in the Forensics Centre in Chiang Mai, with a letter from my school.

The Teaching Council in Ireland has rejected the document on the basis that they believe it it a third party agency that completed the process, and that the document was not processed in the Special Bureau in Bangkok. It doesn’t look like the attached image, it is just the document with the fingerprints stamped and signed saying that I have no criminal offences.

I’ve been trying to contact the police clearance centre to verify the validity, but their email does not exist and keeps bouncing back as invalid. The number provided also can’t be contacted outside Thailand.

Can anyone advise or provide a valid email for the police clearance centre?

Thanks!
