It looks like the service in this company (which makes the Dreambox) is deteriorating for the following reasons:
I sent them my box from Arab Emirates for repair. They dont have a reliable dealer for repair anywhere other than Germany. They kept the package waiting in the post office for 1 month instead of picking it up immediately. After that I waited 6 weeks which is the time they said it takes to start the repair, but they still didnt repair it by that time. I asked them to return the box to me even without repair because I did not want to wait forever.
It is clear that this company doesnt care about good reputation and good customers' service. If the box needs more than 3 months to be repaired then it is not worth it to buy a dreambox. Most reputable international companies have maintenance centers in several parts of the world not just one center in the main country. Dream Multimedia has a sales dealer in Dubai but they told me it cant make hardware repairs.
It is wise for those thinking of buying dreambox to think again. Unless you live in germany near that company, you are going to waste a long time if your device requires repair.
