I've had my SGC since 2013, bought an AYA No 4 in 2014. The RFD accidentally put the wrong serial number on my licence (only one digit in a 6 digit number mind). I asked them to change it on my cert which they did. I then put the correct one on the letter to the Thames Valley Licensing dept (I think), they must have put the wrong one down... my licence was getting very tatty indeed and ripped so I sent it in for a replacement. Just received my replacement but it has the wrong number on. I've just emailed them asking what I should do but I'm a bit worried about getting into troub.
How worried should I be and what could the consequences be?
