It starts with this:

I was given 6000 XLM and I left it in their official wallet for years. On May 12th, 2017 I wrote them an email asking why my wallet, now converted to some newer official wallet, was empty. I did not receive a reply for 2 months, at which point I followed up and received a reply within a day, which was:
"I have investigated your account and it looks like an account merge operation occurred some time ago merging your lumens with another account. If you did not commit this action, it could be possible that someone was able to obtain your account information.
You can see the merge operation here: https://horizon.stellar.org/accounts/GD2CPSK2E3TUNC2N5NGGQJQ....
Unfortunately there is nothing we can do to retrieve your lumens at this point.
Apologies we cannot be of further help."
