DQN Customer ServiceWe are here to serve you

We realize that without you, our customer, we wouldn't be where we are today and that thorough and timely service when a problem occurs is paramount to our continued success. That is why we have made the process for solving your problems as easy as possible.


Many of our customers told us these pages were helpful in answering their questions, so before calling or emailing us, take a look at the following:


Warranty and Return Policy

If none of the pages above were helpful, then please give us a call at +84-8-3152-6377. We are available from 8am - 5pm ICT Monday through Friday.



If in your urgent case, you can call us via our hotline at +84 91 93 99 582



If you prefer to contact us via email, or if it is outside of normal business hours, please write to us, we will respond to you as soon as possible (we check our email at night and during the weekends - remember you are important to us).
