Kobo stuck on a screen and it cannot charge

Hi Kobo Support,

My Kobo Colour Libra has been stuck on a book cover page, being unresponsive to anh touch or button response. I tried charging it, but the charge light usually does not.come on (only sometimes, but most of the time it does not indicate that it is charging). I am also unable to switch it on/off or restart it.

My kobo's warranty has sadly expired. Please do help me in this, thank you!
