Well, the best resort remains to engage a solicitors and serve the tenant a written notice. If you need one you can find them from The Malaysia Bar website.
This was taken from the link shared below:
1. Serve Written Notice (with AR Registered post)
2. After all notice had been served and still no further action being carried out by tenant, file a court order in the session court.
3. After court order had been obtained, you can then proceed to go to TNB to ask them to suspend the electricity supply and start making a police report
If you suspend the electricity supply without prior notice, legal action can be taken again the owner itself and nowadays, you cannot just make a police report and changed the lock thereafter.

Btw, who's that agent? LOL. And which area is he renting? Need to avoid such tenant with a bad credit.
