I already had a license for 8 years.. I am re applying after revokation, the guy on the phone told me about the appeal procedure but when i asked on what grounds it had been refused he could NOT tell me saying after checking my case he could not see a reason why it would have been refused so he has sent it to a manger to re check it.. He thinks there is a mistake

Hi i was looking for some help on an issue with the DVLA. I had to go for a dvla medical on 7/4/14. I was told my results would be 3 to 4 weeks, i waited and on the 5th week i received a letter from them say it will take a further 12 weeks to be reviewed! i waited again but after getting a job offer i contacted them to ask why it was taking so long only to be told its in a queue.. This has been almost 150 days from my application.. I emailed complaints who contacted me today to say they received my complaint and they checked my case and unfortunatly i have been recommended not to drive for road safety! I called them instantly and asked the guy on the phone from dvla on what grounds has it been refused... He said he will check the file.... Um 2 secs... Ohh, i just need to read this there is quite alot, il put you on hold.. After 15minutes he comes back to say him and his colleage next to him doesnt know why the licence would be refused by the information he has. . He said he will get a manager to check it over asap.. high priority and if i receive the letter i got in the email in my mail i have to ignore it.. All this happened about 2olclock.. I never received a call! Has anyone been in this situation before or anyone know what i should or can do about it.
