HELP I DID NOTHING AND I GET BAN HELP!!
Welcome to the PlayStation Community.
Actually believe it or not people get suspended or banned all the time Moble.
To the OP, even though right now you say you did nothing wrong, if you have indeed been suspended or banned it will not be for no reason, Sony doesn't choose to suspend or ban someone lightly, it only happens after a pretty thorough investigation, so like I said there will be a reason for this.
You should receive an email within 48/72 hours of the suspension or ban explaining the reason(s) & length of any suspension or ban, if you do not then please contact Sony customer service.
