This has happened to me as well. Who's fault? Hotels and SPG. SPG allows hotels to modify our account information. So if a hotel you recently stayed still has your old address, they might decide to "update" it for you. I even got my Name changed to my old name once......

I don't understand why SPG allows this but you are not alone here.

Is anyone else having this problem?
I don't want my new SPG card to be sent out to my old address!
