MetroV SurveyOnline news reportData from the most recent commuter survey paints a bleak picture for MetroV, the private company tasked with running the city’s public transport network. Customer satisfaction with MetroV services has fallen to just over 50%, a far cry from the 89% it experienced when it took over management of the network from the government-owned company NCTP more than a decade ago. With delayed and cancelled trains, and interrupted services on the majority of its city lines, MetroV has also seen a surge in complaints in the past twelve months – the number of complaints received last year is greater than the combined number received in the first ten years of its operations.Dr Sula Klim, head of the commuters' rights group, Comwatch, slammed MetroV over the figures, stating, "We deserve so much more. Our public transport system has become a laughing stock. MetroV is not fit to run this network."MetroV has yet to comment on the survey data. CommentsRashid: The public transport system is no different to what it was twenty years ago. There are just more people complaining. It’s so much easier to complain now than it was in the past. In those days, you had to handwrite letters and post them. Now, having a moan is just a click away.Barry: Yesterday, I had to wait thirty minutes for a train when the supposed waiting time is seven minutes. Bring back NCTP!Karli: The definition of ‘satisfied’ has changed over the years. People used to be happy if a train turned up. Nowadays, they expect transport to run perfectly on time, all day, every day. And if it doesn’t run perfectly, they are ‘dissatisfied’. I blame social media – it presents perfect lives, and so people seem to think they deserve perfection. They need a dose of reality.Amanda: The survey is so biased. It was hosted on the Comwatch website – a place where people intenionally go to complain about public transport. What do you expect?Roland: I am a retired train driver who used to work for NCTP back in the nineties – in the good old days. The problem is that MetroV operates in the interests of its shareholders. The changes MetroV has made to services are solely to increase profit. That’s what happens when you use private companies.Question promptWho shares a recent personal experience of travelling on MetroV trains?Question response areaSelect one optionRashidBarryAmandaRolandNext
