"Really bad customer service"

Booked an appt with Chiropractor recently, was told initial consultation would be £45 for 45 minutes. Called in at 8:25am out by reception but 8:55, I asked the receptionist to find out if i would have to pay the £45 or £30 for 30 minutes (which it had been), she said she would enquire and tbf this receptionist was nice. I went to pay - they don't accept card payment. Said I will have to go into Skipton she said fine, she was waiting to hear back from Chiropracter regarding charge.. When I got back to the surgery there was a note on my car saying for patients only and not to park there, well I was a patient (a paying one at that) and if the person who had booked my original appt had mentioned on the phone cash only, I wouldn't have had to trek to Skipton. Anyway receptionist said £45 for initial appt and he had done all he could in 30 mins, well charge me for a £30 mins appt, I'm not tight and work in the nhs myself, but I don't think anyone likes to pay for time they have not used. Spoke to the Practise manager about note on car, she said she saw me get a mountain warehouse bag out of the back of my car (that was correct as I had a brolly inside, in case it rained) and go to into town. I said that's because no one told me it was cash only. If she had spoken to the receptionist she would have known what I was doing. The car park is for poorly patients coming to see the Dr, which I understand but there was loads of space in the car park when I left ( wish I had taken a photo). If you have time to watch the coming and goings of people in the car park you can't be very busy, maybe a practice manager is not needed at that surgery. I was out of the car park by 9:15 which was suppose to be my actual appt time finish
