Free Traffic Legal Advice

So a while back, I received a letter from Sippi asking me to sign up for an e-permit for my apartment car park as they were moving over to digital permits. I applied through the website and uploaded a letter in my name as proof of residency. This was rejected as they would only accept a utility bill as proof which I didn’t have as I am not the one in charge of paying bills. I sent them a message stating this however I received no response.

A few weeks later I received 3 parking tickets in the post claiming that my car wasn’t registered to use the car park.

I appealed the tickets but these were rejected and UKCPM have no phone line or email to discuss parking charges so I contacted the building management who are completely useless, take ages to reply and claim they can’t help me until they sort the property accounts with the leaseholder (my landlord). My landlord emailed them twice and they stated that someone would get back to him however it has been weeks and there has been no response.

I have now received two debt recovery letters claiming that I have made no attempt to respond to the fines which is completely untrue.

Am I better off paying the £510 or should I let them take me to court?

Also, I still had the physical permit displayed in my car during the issue of the tickets and I also pay a monthly fee to use the car park. There was also no mention of a specific deadline to switch over to digital permits.

I would greatly appreciate any advice
