What happens in this situation...

You ask the csa to look into a decision and then change your mind much later?

It depends what you asked them to look at and if they have already acted on your request and reviewed the decision. If they had made an error and you asked them to correct it changing your mind later would not make them ignore the mistake. However if you challenged a decision about a variation and then decided you no longer wanted to challenge it I think you could withdraw your request for it to be reconsidered - assuming they hadn't auctioned the request. Perhaps if you give a bit more information someone will be able to help.
