Why there isnt any zero star? One word, speechless.I tried to link my credit card to my son's 16+ Zip card for auto top-up. Waited long enough, connected to a operator. Explained what i wanted, they said, I will transfer to the correct department. Repeated 4 times. Each person I have to explain the same story. Still I couldn't get to the correct department.Why do they get paid for? One of the most expensive travel cost on the planet and the worst service on the planet.
