I'm a in-house translator at a company. We sometimes test new freelance translators to help us when we are short of in-house resources.
One of our criteria for collaborating is to have the same tool as we have.
Lately, a potential freelance who has a different tool insisted to be tested by us, telling that she would get the same as ours if she succeeds in the test. Thus, I made an exception, asking her for specific file-formats for delivery.
She delivered one file in the right format but in a very different way as the source format and could not deliver one other format. Thus, we can see/test the translation but we cannot use it and we need a lot of extra work to fix it (although we wanted to save time by outsourcing).
When I asked her to deliver another format, she criticised our recruitment process and was very angry that the technical aspects are as important to us. She will not send us the bill and doesn't want to hear from us any more.
I fear for the reputation of my company and mine. I want her to understand that the point is not only the technical aspect, but the manner she deals with us as a client (not helping to find a solution). How can I answer her mail in a professional way?
I simply want to close up this encounter in a graceful manner.
