I finally phoned the DVLA and got a human eventually, or at least I think it was. They advised that they would have to instigate an investigation in to what has gone wrong and it could take a couple of weeks..?? So that I could tax my car, they suggested, "Contact the person you sold your other car to, ask them if you can order your tax disc, which will then go to him, then ask him if he will send it on to you, that way you can get your car taxed". For crying out loud, why not just change the incorrect owner details, which would take 2 minutes and sort the job out properly. No it has to be investigated before we can proceed, so this is the only way you can tax your car and be able to use it.....!!!!!!!! IS THIS THE UK...???
