SanDisk Ultra 64GB microSDXC dead..

Not sure how or why, but semi recently my sd card died unexpectedly. I turned the phone on, and it came up with the dreaded Card Not Readable message. I’ve tried in several different devices (laptop, tablet, usb adapter, etc), and the card is dead as dead can be. Isn’t there a warranty on these things? I’ve had it less than a year and it died over a month ago.

10 year warranty
