Dear Sir,

I would like to make a complaint about a driving test which I was given the 5th of April, 2001, for which the instructor failed me saying I don't understand English. The £80 test was supposed to last forty minutes but he took only twenty minutes. I don't think I misunderstood any of his instructions and I performed all that he asked of me. Please refund the testing fee, which I plan to use for another test where I can prove my command of the English language.

Yours sincerely,

Mr. Hassan
