When returning from holiday, collected car, put ticket in machine and message on screen read payment due £141.00 had to reverse, queue of cars behind pouring with rain!! went into the office and explained to the young woman behind the counter, who had NO customer service skills, she was abrupt in her manner, I got my confirmation letter out showed her, she printed off a new ticket stating "this will now get you out"- no apology or explanation.... took the new ticket out (in the pouring rain and pitch black) put it in machine and machine wouldn't accept it !!! my husband got out of the car _huge line of traffic behind ,,,, could not reverse a man came out and had to fix the machine, he was very pleasant.
