Help with letter of complaint to the editor - see news article

Dear All,

Please see link below to an article about 'soaring' PIP payments for 16-17 year olds.

I would like to write a letter of complaint about this and understand the best place to start is to write a letter to the Editor. I was wondering about your thoughts about this article and about how I should respond.

Many thanks in advance,

Mrs Snooks.
