I've recently been contacted by a company called Advantis to advise I owe the DVLA £180 in unpaid fines for no tax and no insurance. When I asked for details, it was related to my old car because the DVLA said they did not get the new keeper details I'd sent in to them. They said I should have contacted them four weeks after posting if I'd not heard from them, however the same week I'd moved house. I've appealed this as I'd sent back the documents. Also I updated my licence in the same week. So the DVLA did have my new address but made no effort to contact me in relation to this matter, they simply passed it onto a recovery agent. Do you think this is worth fighting? The garage I sold my car to are a big firm and are happy to step In to provide proof I didn't have the car at the time of the fines being issued.
