badyzh Cyprus is in the EU (European Union) so you  should be able to escalate to the UK and maybe they can find help for Cyprus? Since you can only call because you don't have a Service Tag Number, here is the phone number to the Dell UK 0844-444-4712.  Z.................
Hello. I'd like to complain about the quality of support for the countries not represented in the Customer Service panel. I live in Cyprus and my Dell U2412M monitor stopped working: after that I tried to contact your twitter support (who told me to provide my details which I did: silence followed), some of your support staff right here (same story) and after that I was able to found an authorized service provider here in Cyprus, called ASBIS. A man there asked me of my Dell order number (as if he didn't know a Cyprus person can't order directly from Dell thus can't have a Dell order number), then told me they can't help me if I don't have it. When I've sent them here which explains how support is performed in case of resellers (my reseller is amazon.de, I can't imagine more legit reseller than amazon) along with all details necessary, after that they have decided to ignore me as well. What do I do to get my monitor fixed, it still has 2 years of warranty left? Thanks in advance
U2412M, no Service Tag, Amazon purchased
