So I called to make an appointment for a stamp in my passport. They were very helpful, called me back the same day and my appointment is set for next week.
However today I had a new extension letter arrive, I had an 18 month one, then a 24 month one. Now I have 48 months! Great…I don’t mind that at all. Although I now need to cancel my appointment lol. Also don’t understand why I wasn’t notified of any post heading my way, all signed up online so that’s weird. Still I have another two years for them to look at my paperwork so that’s fine by me. Especially as I can now get my driving license sorted.
