So the option is then to visit the main post office in the town,
necessitating finding and paying for somewhere to park and then having to
queue for 20mins. I detest all aspects of that, so if there is an on
line option, that will be the next solution.

Worst thing they ever did introducing single queues. At least before you
could see
who was in which queue and make an informed decision on who was likely to be
banking £20 in pennies

Single qs with incessent adverts for insurance savings schemes blaring
away... bit like the "your call is important to us"
nonsense. Bring back the engaged tone if companies cannot be bothered to
answer the phone
