Suspended account? With no reasoning?

Depending on how long your suspension is there is a way to appeal it if its longer than 24 hours

Enforcement How to submit case review. Good luck!

Since your a newer xbox live member, perhaps another gamer and/or gamers filed complaints against your account through xbox live. Some people do this with or without a reason.

It's only the single player that is rated,the online aspect is not rated.

It's not a case of "manning up"

If you can't respect other people online then perhaps you shouldn't be playing online

Some people don't like to be swore at,screamed at etc. & they have as much right to go on xbox live as you do.

I have physical & mental health problems & so do many others,not sure why you felt the need to mention that as it has nothing to do with xbox live.

Might be worth reading the Code of Conduct

No one can help me on there either that is why i am posting on here. So where can i find actual help?

Xbox enforcement don't have a way to contact the other then submitting a case review. I think that would be the best option. Otherwise you can get in touch with Microsoft legal team since you stated you are taking legal actions.https://www.microsoft.com/en-us/legal/compliance/integrity

This is from the Xbox Enforcement site:

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.
