I think you'll find Dell has no corporate presence in your country -- all service and support is handled through retailer/dealers.  Contact your seller.  
I live in Tbilisi, Georgia  (Country in Eastern Europe) and wanted to contact Dell Customer center (I've bought laptop a month ago and has motherboard failure). So, whom I should contact, what is phone number of Georgia's Dell center?
What is Dell Tbilisi, Georgia contact number?
