Disgraceful service. Far too over priced compared to all other car parks in central Glasgow. Stayed for 2 hours and 29 minutes costing £9.90. I has put in a £5 note and realised I didn't have enough change on me, waited barley 2 minutes for my sister to run down the stairs with more change and the machine cancelled the transaction, without giving back the £5. It then gave me an IOU slip with no contact number or details what so ever as to how I would get this money back. I am a student and £5 is a lot when you are on a budget. Still trying to get my money back!
