3 Days and counting - no resolve to G Ultra device not working

Terrible technical telephonic services. Would not recommend if youre looking for a system with a technical support system! On the logs I can clearly see that our system stopped operating after a firmware update. And MANY calls through to their technical department leaves me with a guy with a foreign accent difficult to understand what he is saying and he was going to escalate the issue with their tech dept and still no call back no follow up and no change to the issue on the device. I called the number again got through to another guy who gave me a reboot code to sms, also no joy. Tried calling back again and now IF i get through to a technician- it goes straight to voicemail and the inbox is full. Really just unacceptable.
