Not sure if the clamping ever happened, but threats were made... Think a "2 car per CP" limit was trying to be enforced when I was there. Some CP's would have a few cars, and the car park became very full. I didn't see the problem though.. People buy a car, they expect to be able to park it where they live !!
The internet issue - we were continually assured that investment was being made to improve the service. It never happened when I was there. The 5mg limit was enforced however, you would be cut off with only access given to CTC email and the ops website if you reached the limit for the month. Not great when you wanted to skype home, although skype was a comical experience with the internet connection anyway.
Like all things, nothing is ever perfect, but the way in which some of the 'problems' were managed was hilarious.
