Forgot to pay congestion charge last Monday

Tried to pay today when I remembered but it seems I can't. Website talks about receiving a penalty notice. Presumably this comes in post, anyone know over which timescale? Penalty seems severe for a mere oversight.

You can register an account. That way you autopay when you enter

I've got a few vehicles on my ac

Other than that, you break the rule you pay the penalty (still hurts tho)

It's a bit like a parking ticket if you pay within 14 days you pay half price.
