Totally unreliable business with zero accountability. Drivers often cancel ten minutes after accepting your ride and Grab doesn't automatically find another driver so often left in the lurch. Increasingly have issues with other Grab services. Recently, Grab cancelled my dinner order over an hour after ordering, claiming they couldn't get a driver. That's their core business, alarming! At that point it was too late to make other plans. I contacted support three times, still not resolved.
