I got my council tax band changed saving myself a few quid along with a backdated payout. I have several neighbours still overpaying despite me telling them, one mumbled something about his house being worth more if it's in a higher tax band

If "Vera" is on a low income there may be additional help available via council Tax Reduction. Rules vary between local councils but worth a look at yours if you're concerned. Likely buried away in the bowels of their site.
Though generally if you have more than single digit k's savings you don't get any help. Vera saved her money for a rainy day. Unfortunately that rainy day is her new council tax bill
It's about time they came up with a fairer way of calculating Council Tax, basing it mainly on property prices is daft. But that would require thinking and Politicians tend to overheat if they think too hard.
