Subscription given to me on Xbox One console game.

Folks I may have missed something I should have read but I have not been around for quite some time. I turned on my Xbox a short while ago and it patched up and everything like it should have but I now have a subscription to ESO Plus that I did not order or pay for. If this is something that Xbox was supposed to get then I missed the announcement and need clarification. If it is not something I am supposed to have then I need ZOS to remove it from my account. My gamer tag is CJMC1973. I have checked and none of my cards have a charge for this on them and it my account it shows that I don't have ESO Plus.
