***** company try your best to avoid

They are definitely not a trustworthy company. They lack professional communication channels. They mark some documents and varified without even contacting the institute that issued the document, I know this because I provided them with a work experience certificate from a hospital where I worked, and it happened that my boss in the hospital was one of my friends ;-) who told that they never contacted him!!! In the email I received from them, links were broken.

They keep sending you the same email, and they ignore your questions, to clarify what they want, and keep sending you a sentence saying "DataFlow Group would like to remind you that the deadline to fulfil the above requirement is no later than *********** in order to avoid classifying your application as Unable to Verify (UTV). Kindly note that once an application is marked as UTV, re-verification may result in additional charges." It is clear they are trying to gain time, till the date is passed, so you pay more fees for the re-verification!!!!!!

Last thing to mention I PAID THEM about 500 EUROs (over 750 USD)

I really can not understand how comes such a bad company can be trusted in the Arab Gulf States such as Dubai, Qatar, ...
