Its 4 months to the day (give or take) since the Citaros, decked out in their branding and wifi advertisements were introduced on the 4 and despite the company knowing all about the wifi not working, they have not fixed it judging by the comments above.

Maybe passengers are as apathetic about it, as customer services seem to be.
Just relieved it was GNE money that has been put to waste and not any of the public money mentioned in the bus fund thread.
