Hmm,
About the costs you had to send it back:
For all I know is that in my country they are bound by law to refund the costs that I have to make for getting/sending the product RMA.
You should check if this is also the case in your country.
What follows next is something I see more often these days and is not pointed at SanDisk(they handled correct and polite in my case)
Most of the time the companies are aware of these laws but unless the client specifically “makes them aware of these laws” they won’t pay you back your costs.
