I had issues with my c240 firmware and Sandisk Technical support as result my c240 became inoperative.
Today I have called Sandisk Corporate office at 408-801-1000, and complained about their Trchnical support
to Mr. Kavin a highlevel customer support person. He promissed will solve all of my problems, he was a nice man, contrary to those Technical support people.
Really when you can not get result from customer service, or Technical support must complaint to Corporate Office and they should be aware of the problem.
