Maybe so but the council aren't psychic. Just because there's a problem it doesn't mean that the people who can put it right necessarily know about it. In this instance HBC aren't directly responsible, it is LCC, so it will be down to the speed of the organisation that takes 80% of your council tax.
However, I'll just reiterate my point that we're only as good as the information we're given so please don't stop telling us when something isn't right.
