Parked at Gloucester Blackfriars car park, put the £2.50 for 1 hour parking in to the machine which failed to issue a ticket as I had entered my car reg I thought I would be ok, next I go a £60 fine which I appealed. I was sent an email to say that I had failed on my appeal as their machines were working, believe this to be a standard response, I'm now of the opinion this is their way of making extra revenue so never again will I use their over priced run down car parks,
