had access to some sort of 'system' that had my details etc?

I had a similar situation last Friday. I subsequently heard on the news
that the govt was thinking of bringing down the in-between time from 12
weeks to 8 weeks.

I had first AZ 10 weeks ago, and was booked in 2 weeks to go back for
2nd, at nearby NHS mass vaccination centre

On Friday, I saw a posting on local Facebook page that local vaccination
centre (GP run) was offering second AZ vaccines for 8+ weeks. I was in
the car immediately. All went well. On arrival, all done in 30 mins
car-door to car-door. I asked if I should cancel my appt booked in 2
weeks or if it would get cancelled automatically. The lady said she
thought it might get cancelled, but I should check. Came home and left
it a couple of hours and checked online and appointment still there, so
I cancelled it. All fine: it was booked and cancelled via
nhs.uk/covid-vaccination

I think you should try and cancel your now unwanted second appointment:
it might help someone somewhere!
