Well, it's a mistake but that's a thing of the past now. It's unchangeable and I don't think .amaZe would do that purposely. Why would he purposely do it so he could ruin his own reputation. It's true that he forgot to back things up but remember that he's a human like you and we all make the same mistakes.

I think he would be glad to give you a refund if you weren't happy with the result.
