There appears to be an issue that has been happening lately. It appears that if an enforcement action was extended then there may be no additional notification and the enforcement site does not reflect this extension. The only way to currently find out if
an enforcement action was extended is to contact Xbox support.

I will give you an example of how you can be suspended when already under a suspension.

It takes time for the enforcement team to investigate suspensions so say 2 weeks ago you sent a message to someone that violated the code of conduct it gets reported and the enforcement team does not get to the report till today and puts a suspension on
your account for say 1 week starting from today.

Then 1 week ago you sent another message that violated the code of conduct and say 2 days from now it comes across the enforcement teams desk they would then add a 2 week suspension to your account.

I am not saying this is what happened to you because I am NOT a part of the enforcement team I am just giving you an example of how you could get suspended when already serving a suspension.

As far as the case review process goes you do need to answer all of the questions correctly in order to be eligible for a case review the answers to the questions can be found at the enforcement teams website enforcement.xbox.com

Just a friendly reminder though that it does not mean that we have appealed it will be taken off. It may take some time as well for the enforcement team to check your request.
