A suspension problem

You can view your ban by logging in at enforcement.xbox.com and
from there file a case review if the ban is eligible for one. The enforcement team does not use the forums and the case review process is the only way to contact them.

If you feel your account was accessed by someone else you can contact official support to open an unauthorized access case. support.xbox.com/contact-us

Hi there,

please double check http://enforcement.xbox.com to see if there are no enforcement actions active

If the all is clear, try the following steps

Remove profile from the console (Make sure you know the account credentials for the account, since you will need them later)

Perform the manual power cycle steps like mentioned on the following link, be sure to wait at least 60 seconds before powering on again:
http://support.xbox.com/en-us/xbox-one/console/power-cycle-console

Redownload your profile

If these steps fail, then its best to contact Xbox Support (via Phone or Microsoft Support Chat) at
http://support.xbox.com/contact-us

Let us know the results

Unfortunately your have to just ride the ban out sadly, I myself have been clumsy enough in the heat of the moment to swear at someone before and was coms banned for a week, Best thing to do next time is report and block, easier said than done but best
for your account safety.

Not worth getting baited into anything.

Keep in mind the following rules of thumb regarding Xbox Live suspensions:

• Generally, suspensions end at approximately the same time of day that they are issued—not at the beginning of the calendar day. For instance, a 24-hour suspension issued at 3:00 p.m. will end at approximately 3:00 p.m. the following day, not at midnight.
• Microsoft is not obligated to provide a warning prior to issuing a suspension or other enforcement action. By agreeing to the Microsoft Code of Conduct you acknowledge that you understand and accept the rules of the Xbox Live service.
• The length of the suspension depends on the severity of the offense. Especially egregious violations can result in an immediate permanent suspension.

I wasn’t doing anything wrong when I got suspended. Why did this happen?

While some Code of Conduct violations are immediately resolved, XBLPET also conducts reactive investigations. Many of these investigations are triggered by player complaints. The Code of Conduct has no statute of limitations, and users may be enforced upon
at any time for past offenses.

A player may be offline (or playing single player) at the time of the suspension, but his or her online status at that particular moment may have no bearing on the reason behind the enforcement. If you receive a suspension and are not sure why it occurred,
please check the email sent to your Microsoft Account or view your Enforcement History on enforcement.xbox.com.
