We're not HP Tech Support and we have no way of sending any service reps to your location.

Since you live outside the U.S., here is a link to HP Service Centers, by Country/Region: https://support.hp.com/us-en/service-center

If that link does not provide you sufficient information, then use the main HP link:
https://support.hp.com/us-en/contact-hp?openCLC=true

I've found those links to be unreliable if you're using Win10 and the new Edge Browser; so if you are, you need to use something else, like FireFox.

Good Luck
