Skrivanek LTD - Scammers

I would like to share the experience of working with Scammers - Skrivanek LTD (LV). When we have worked with little projects (many language pairs), the payment was regular. The sums were small, so we have payment every month. But our cooperation wasn't so long as we expected. Managers of Skrivanek LTD gave us big project, which contains big and little files. We have done it partly, they have no claims for the quality, and when we have finished this project they refused to pay it referring to bad quality. With it they don`t want to pay another projects, also trying to say that the quality are not good. To prove it, they have sent files that we have never done, as I understood they were from another subcontractor. They proofreader project themselves and gave no choice to see it for us. To conclude, I would like to give advice not to work with this company, they will never pay you, even than the work will be done good. This company said, that they have additional expenses, but no proofs as well as proofs of the clients failure to pay.
