Travelled to Manchester to see a concert at The Great Bridgewater Halls.. Large banner on Watson Street advertising Parking for £6 for 6 hours after 6pm. Do not be fooled!! The banner is positioned on the right side of the road on a mini roundabout at what turns out to be at the exit of a NCP car park. The only entrance to a NCP Car park on Watson Street is on left hand side of the banner, on the mini roundabout ,where car park charges are not advertised. On returning to my car after 3 hours 40 minutes the machine demanded £17. I used the call button. No response for 10 minutes. Other angry people around the pay machine. NCP staff on the other end of the call button were clueless. Promised to call back. Nothing happened. After 40 minutes two guys arrived...unhelpful and claimed they did not see the banner on Watson Street. No point in contacting NCP customer support...they have no idea what this means!!!! Does the C in NCP means cowboys?
