Just consult DTI at baka may maitulong sila sa kaso mo.
Palabra de honor dapat pinahalagahan.
Nakakasama talaga ng loob ang nangyari sa iyo.
I'd agree with a DTI report.
Put it in writing to keep your experience recorded at the proper agency/forum.
If nothing comes out of the report, at least you did your part in letting the agency know what happened.
If they don't act on it, that's there decision and they can face up to any consequences it may bring them.
IIRC, DTI as an agency is tasked to safeguard good business transactions and they cannot perform this if they are not made aware of potential wrongdoings.
Another option has already been posted, TS may also just let this incident go.
But there might also be a consequence to that.
