I made some mistakes, but still the translation was done and submitted to you.
I made a huge discount because of the mistakes and you still have to pay, because the work was done and submitted.
The proofreader got her money for proofreading, but you still owe me. It is so dishonest not to pay and disappear, not answer letters and telephone calls.
All in all, with all discounts, you still owe me 50 EUR.
