I recently received a text from a No Reply number, saying that I hadn't paid a debt to Bristow and Sutor of £615, and that I should expect a visit from bailiffs and there is a warrant on my vehicle which will be located and seized, but no other details. When I finally got hold of Bristow and Sutor today, it appears that I didn't pay for my dartford crossing back in May last year (a complete oversight). I never received a PCN or any other comms. However, looking back on my phone, I had received a text in December and January from a No Reply number that I assumed were scams, so didn't respond as it did not say who they were from. The advisor today said this text only contact was because I didn't change the address on my V5 when I moved house last March. They had to use a tracing agent to find me, and all they could get was my mobile number. She said they had apparently used the DVLA to find me, who have my up to date driving licence and tax details with the correct address and email/phone etc (the V5 was an oversight of mine), but they weirdly could only use my mobile number to contact me. She said that apparently this case has already been to court without my knowledge. I now have a debt of £615!!!! For an original £5 charge. I am beside myself as I do not have this kind of money, and I am looking for some advice to try and figure out what to do. has anybody had any kind of success in appealing this charge? I am more than happy to pay the original late payment fine as this was obviously my oversight, but £615, seems totally disproportionate. Obviously I do not have any PCN or paperwork to attach, as I have never received any.Thank you.
