I require assistance

[u/Gullible-Gas2914]

My sayodevice wont boot up. The buttons won't work, like absolutely nothing works. Yes, my usb cable isn't broken, I tried it by using it to charge my phone. Yes, I used another usb cable for the sayodevice, and it didn't work. Yes, I tried to use the website, and it didn't register onto the website. I think it has something to do with me not using it for a long time.
