Aquila Translation

I wanted to inform other translators about a cheating company, Aquila Translations from Armenia. They ordered a large translation from me, then after I almost finished it they supposedly cancelled it cause their client supposedly dissapeared. Now they depreciate my translation, say it was my fault and refuse to pay me 800 EUR. If you need evidence, I can provide it. On 16.12 "please proceed", on 19.12 "please hold on" (when the deadline for a large file was 21.12 - I don't know why) - after I have translated almost everything. And then no message for over 10 days after many attempts. Besides, when they need sth they answer within 5 minutes and when they don't, I can't get an answer for ca. 10 days. They also changed their version a couple of times which suggests they are trying to lie. Then they said "give us some time, of course we will pay". Next week : "of course we won't pay, it's your fault".
