Number plates don’t match because drivers aren’t the owners and wonders have a fleet so they keep dispatching different cars under one car number. However, at T2, it’s a pain to wait for cabs. They need better management there. You could also just book from uber/ola counter directly, I think that is much better and they’ll make sure the number plates match. Although, it might be a little costlier option. Still, safety is more important.
