Bad experience with cancel feature and communication

My 1st use of the service, I had a problem so I couldnt take my ride => not possible to cancel a ride!
Go-jek called me 19 times to know where I am!! 19 times... Crazy...
Im sure the service is convenient though, but they have to improve their cancel feature and stop harassing people when they dont pick up the phone
