Ok thank you DX. Will get that up tomorrow. I used to be Vamps

This morning I received a letter from DR+ demanding £170. The date of parking charge was 23/10/20. The letter says they have 'traced' me to this address because letters sent by Smart to the address the DVLA hold for me, were not answered. At this point I should point out I moved from Surrey to Leicestershire in 2018 and I registered a change of address with the DVLA. My driving licence is this address and though I have been unable to find it today, I am pretty sure I would have changed my address on my V5. Now, I can confirm I was at the car park when they said and yes, no payment was made because despite trying several times, the one and only machine said "Cancelled. Printing error". I know because I photographed it, just in case. I gather I ignore this demand but I have never had a parking problem so I would be very grateful if you could advise me of my next move please.
