national mileage database issue

[Beans on toast Dave]

I am purchasing a vehicle .

Whilst I was at the garage, I asked to have an up-to-date check on the vehicle. They asked what the mileage was, and I said 4200, as I did not realise it needed to be the exact mileage.

This has now caused the vehicle to show a mileage discrepancy.
How can this be rectified? can it be sorted? ive contacted the garage and they are not too helpful really

to be clear the garage has it advertised for someone and its in effect a private sale

not sure what to do as

i was enquiring about a vehicle and said i had done a Hpi check on it and needed some details to verify the check Eg V5 issue date and serial number
the mileage at this time was ok on the Hpi check
they did not have the V5 to hand so offered to do a check there and then (yes i will get the details for my check later) he asked me the mileage and i knew it was 4200 give or take so just said that
now the my hpi check is saying descripancy the last mileage was 4206 and i said the current was 4200 as i had just taken it for a test drive and its just flagged it up
its not the end of the world i just would like it corrected if possible
