Sembcorp Parking in NUS

Yea... They totally suck. Why are we paying for the parking when we are already paying 20k for the campus facilities and stuff? Which comes to my point. Spent an hour today arguing for my 15 bucks exit fee from the carpark at SDE. It was like WHAT?! 15 BUCKS?!
Its a university for FARKS sake and i am a STUDENT, not like i'm some outsider trying to park at NUS. So i called the sembcorp ppl, spent 5 mins talking to the intercom person, which i think has totally no control, she keep saying "yes sir, u have to pay the parking fee coz you parked there" , nothing else. How bout I get someone else who has control man. So I called for her superior. Argued awhile, made a fatal mistake (always think before you argue against each argument), when he said "so you are playing with the loophole?", and i replied "yes". Omg, I am one brainless guy man. Then some further talking and arguement, i managed to get him to only make me pay for today only, which is like 6 bucks. The whole thing started coz the nite before I went out and the gantry was up, so I din pay the $8.10 which was indicated. Today morning I was so early that the gantry was up and did not register my car going in. This resulted in the gantry system think I did not go out yesterday + the time i spent today. WTF lo, what kind of stupid system is this. After 5 mins with the intercom person, I called for the superior. Argue here and there, what a waste of my time man. He keep saying they also know about this flaw and they were in the process of changing it into a 24 hour system. But what the hell, now is now can, stop telling me about the future. So after 20 mins of going near the gantry and back out, coz they cant seem to reset the time for today only, (finally argued until i got them to count for the parking time today only), they sent someone over to solve it manually. Then again, I have no idea what are they doing, still cant seem to solve it, or set the time back till this morning only, they finally opened the gantry and let me go without any cost. At least they did not tell me that I had to pay them in the future or whatever. YES, I won for the moment! But sigh, think i'll have to hide my car for a week or so.
