HMRC aren't just rude, they're breathtakingly incompetent too.
I work in childcare, and at this time of year we get loads of enquires from HMRC about people on tax credits, to see if their real childcare costs match what they claim they're paying. Occasionally you get someone vaguely intelligent on the phone, but most of the time it's as if you're talking a foreign language.
One recent example. A single mother with three children got a very snotty phone call to say her tax credits would be stopped and they would be clawing back past payments because she hadn't been paying a penny towards her childcare. She phoned us in tears, so I got on to HMRC.
Me: "Why are you saying she hasn't been paying for her childcare?"
HMRC: "I have the statement here and there are no payments on it."
Me: "Can you see the labels at the top?"
HMRC: "Yes."
Me: "What's the label on the third column?"
HMRC: "It says 'Payments'."
Me. *deep breath* "Well, that's the column with the payments in."
HMRC: "Oh. I wondered what that was. It's not very clear what those figures are, is it?"
Me: "The figures with 'Payments' written above them?"
HMRC: "Well, I suppose it sounds clear when you say it like that..."
Me: "What did you think those numbers were, then?"
HMRC: "I don't know. I didn't really look at them..."
Me: "Did you not think it was odd that we'd give someone childcare for a whole year without getting them to pay?"
HMRC: *silence*
Me: *getting more patronising now* "Did you not think that perhaps that was something you should check before cancelling her tax credits on a whim?"
HMRC: "Ummm..."
