Yes, that's why I posted it here :-)
It's only $2.50 in total, and my company pays it anyway, but still it seems weird that I have contacted them 10 times and no reply, and it just seems a hole in their process that they haven't thought through. Usually they respond very quickly to fraud.
Anyway next time my strategy is to change the destination to a place very close to the pick up place and let it hang, while ordering another car through GrabCar. In the meantime until they respond I will decrease my usage of Uber to situations where I don't have another choice.
