Thanks for your response Lauren.
I have used live chat and yes, they acknowledge that I am missing DataStash refreshes for the last few months. I was hoping that others could chime in whether or not their DataStash balances were correct, or whether it was only my account that had a problem. I suspect that it might be a website bug, but don't know for sure.
I'll leave the thread open for you for now in the event others chime in!
