My experience with tab cab is a nightmare.Their service is definitely not good.
First they book a cab for you at your allotted time and later they say there are no cabs available and on top of that they do not arrive at the given time which is even worst.
The drivers are also very rude to customers, some of them even dont know the destination you want to go.Their app is also not great, keeps crashing.A big NO-NO to this cab service.
