Decline game request

There does not seem to be any mechanism for declining requests to enter into a game that I can find. How do I decline, do I just add a note to the game request or is there a more formal mechanism for decline requests to start a chess game?

You might post how you are accessing the site. There are ways to decline requests in all formats as far as I'm aware.

I acces my games when I get notification that it is my move. However at some stage another member, who I did not know, assumed I wanted to start another game. I have been trying to notify him that I have enough games and do not want to start another game by sending messages but it has not worked. I beleive I have set my settings up so that I do not receive any more requests but it does not seem to be working. I keep automatically being set to "on vacation" because the unwanted game is running out of time. How do I remove this unwanted game?

A challenge that isn't accepted should not cause vacation. If that is happening,  you should open a ticket instead of a forum post.

That said,  are you on the website via a computer, on a mobile browser, on the app? I don't get many challenges so I can't recall right off the easiest place to decline them but can find out. Though,  I would prefer not to search that out for each access method. 

I access via the web site www.chess.com on my desktop computer and most of the time log in to access my games, other times I just access via the automatic email notification from chess.com subject is:

"Chess.com - Your Games Have Been Paused" content:

The games which triggered this event are:

This leads me to a game from member  soumya_kanti_sahu. I have been trying to decline this game but have not been able to. I have not accepted this challenge but it keeps reappearing and all of my games are automatically paused and I am set as "on vacation". All my games have a 14 day "next move time" except for this one which appears to be 3 days.

Stop declining requests. Voila!

I haven't declined any requests, I haven't been able to find out how. Initially I merely ignore the challenge then my games were paused (On Vacation) automatically by the website whenever this particular game reached a time limit of 30 minutes remaining. The full text of the automatic email is:

You may have as little as 30 minutes remaining in one or more of your Online Chess games and because you are a Premium Member your account has been automatically set to "Vacation". Please login soon and continue your games!

It this is the game, you may have accidentally accepted the challenge.

If you hadn't, I wouldn't see it. Just resign/abort. No moves have been made so it won't impact your rating.

That was the game and abort worked. As you pointed out I must have had finger trouble and accepted the game and I couldn't remember doing it. Thank you for helping me I was getting rather frustrated and annoyed at myself for not being able to figure out what to do.
