dvla have a new glitch...one which produced unjustified fines please read as it may effect someone on here

when purchasing a vehicle say middle of month you sorn it[in my case 3 times -2 motorcycles and a classic car]... they do the document change and it becomes untaxed from the beginning of that month-their glitch overrides that sorn-so a month or so later you get a backtax demand from the robbing gits,so when you re-check your sorned vehicle it shows untaxed[despite showing due diligance and sorning it immediately..]
the fines arent valid-they are due to a glitch in the system,so if you get one phone them on the number on the fine letter-i was told mine are sorted but i wouldnt be surprised to recieve further communication
this new system is so poor its unworkable imho,paperless is fine but you can check a vehicle is taxed online and it may seem fine-check a day or so later and it shows untaxed for a month or so previous particularly if the previous owner is slow at sending the v5 away
