Apparently there was a bit of a **** up on the admin part, I had to reapply and was told specifically not to go back to Teddington Post Office. The verification procedure was a bit slack, they did not even look at my ID papers. It seems that hundreds of people were affected. Strange thing is that all my parcels seem to go out from there OK.
Passes are still valid til the end of April, just cannot swipe them.
