We've been alerted to a government complaints service that we have never previously heard of. This is the 1823 call centre, which is open around the clock.
Obviously it's not suitable for all complaints. Illegal parking, for example, would not work since people generally park for only a few hours. But we are reliably informed by someone who uses the service extensively that it works. He gets a response and something is done.
The public have a choice as to whether they phone or e-mail. But the downside with phoning is that you are asked which government department you want, and not everyone might know that when complaining about weeds in the pavement they need the Highways Department, or that complaints about rubbish are dealt with by the Food and Environmental Hygiene Department .
