Battery depleted when not in use?

Still dealing with this issue. Have been given 2 different ship dates but actual shipping does not happen. Accepted different color as mine was not available; still no shipment. Countless chat sessions, phone calls etc, with no avail. I am just about to give up. To be honest I don’t know what the holdup is. I purchased my unit on ebay using Paypal, I did not pay with stones or whatever. Im so frustrated with the RMA process. Sandisk have made everything in their power for me to not want to buy anything from them anymore. Well maybe I can order my own death!; I guess I’ll be inmortal then.
