Then this fact reveal something ....
Having too much booking apps actually dun help at all
U just need a few .... effective one .
The old system of CDG ....
If u dial 65521111 for a cab . U cannot dial for another until the first taxi press meter or NO SHOW .
So this system is good , no one can abuse 20-30 one shot as prank !
When they started sms booking , also impossible to prank ... only this Comfort Booking Apps so big loop holes for pranskter to explore .
