Please, I need serious help. I need to replace two devices, one that suffered from strain on a keychain, and another which I messed up in anger as I banged on it hard. How on earth can I replace the two devices? Go to my local Best Buy in the customer service department? Please help me, because I've broken a bunch of things in anger, now please tell me if this is possible, to go to Best Buy to replace a digitizer tablet from Waltop and a 256 GB flash drive from Kingston?
