The Metropolitan Electricity Authority (MEA) warns that scammers are impersonating its staff via fake LINE accounts, claiming meter inspections and asking for payments. MEA says it does not collect payment via chat, phone or on-site without official documents. Before acting: ask any inspector for their ID card, never transfer money on chat instructions, and verify only through the official LINE account "MEA Connect (@MEAthailand)" marked with a green shield, or the MEA Call Center at 1130 (24 hours). Brief staff who handle premises access and bills.
