Issued a parking ticket but I had used the machine to pay

On 22/04/25 I paid in Pound LaneCar Park and used one of the new machines to pay. I go every week and always pay without fail. I put in my car registration and time of staying. The machine said pay by card below which I did and the machine 'dinged' to say payment gone through and the screen came up with payment accepted and the time I would have to leave. I can see payment didnt go through by the machine did not say that otherwise I would have tried again. I think the machine is at fault because I noticed another car next to me with a ticket and they had also used the machine. I would have asked for a receipt after payment but can see no facility for this. I have paid the fine because obviously you will not accept this but I think you should check your NEW machine's operation and would be interested if anyone else makes this complaint. My Reg No LO11FLB and my payment authorisation ref 1534664346. Notice number is: AA51536590. I would never never leave the car park without paying and go there every week with my Grandson and Granddaughter. Thank you Deborah
