Spent all day on the phone and I've sorted out the tax for the landrover and have a new logbook on the way. They basically admitted their error and said 'oh we've just received the application (which I never made) and you should have it in a few weeks'
In the meantime I've spent 2 days trying to contact the people who clamped me and they've not answered the phone once. When am I within my rights to remove the clamp myself? I can do so without causing any damage to it.
