You should complain as soon as you are aware there is a problem – don’t leave it too long. Problems are often sorted out more easily if they are dealt with early on.
We have rules about when we can help to resolve a complaint, so this is another reason to contact your service provider as soon as you are aware of the problem.
A service provider’s final response should tell you that they have nothing further to say in their response to your complaint and, if you are still unhappy with the reply, to contact the Legal Ombudsman. If you are unhappy with their final response, come to us as soon as you can – don’t delay, as you have up to six months to bring your problem to us.
