Has anyone had anything similar or any advice on this? Thanks Steve

Obviously this is utterly frustrating but DVLA will be subject to all sorts of 'try ons' as well as occasional mistakes over this sort of thing. There is a process to resolve queries and you will need to allow time for that process to progress. That's why they need the photographs etc.

The office would have been closed and/or on skeleton staffing from 24/12 to 02/01 and you're issue came to light just before Xmas. I dare say they won't be back to normal until Monday when schools return.The (say) 10 working day target for this to be investigated will therefore be longer in terms calendar days.

Don't hassle them unnecessarily over the who reported/who is to blame question until the issue is resolved. At that point ask them for an explanation and if needs be seek compensation. Follow their compliants process and involve your MP if you think it would help.

I have to ask why you did not check the mot history online, it is a free service offered online by a gov department.

What level of scrappage, I had one that was scrapped because it was beyond economical value after it got hit when parked, but it was still deemed roadworthy ?

I also do not think DVLA can tell you that info due to confidentially laws.

I would suggest you ask your insurance to find out the full details of why the car cannot go back on the road, they might even be able to get you the details. I would strongly advise you to do as DVLA say and keep the car off road.

I can make some enquiries online if you give me the reg but not promising anything.
