Grab says it canceled heatwave surcharge

It had announced a surcharge of VND3,000-5,000 ($0.13-0.21) meant for drivers.

The consumer watchdog told the Singaporean ride-hailing company that all fees and surcharges Grab payable by customers must be clearly explained before implementation.

It called on other ride-hailing companies to be transparent about them.

Grab was the first to slap such a surcharge after many localities recorded unusually high temperatures, but had said merely it would apply it during "extremely hot weather" without describing what it meant by the term.

Grab Vietnam had an accumulated loss of VND4.36 trillion as of last year.
