My account locked and I am unable to unlock it myself.

My account was locked, unable to use the account. This was more that 3 weeks ago with no communication to tell me it is the case. Now that I would like to unlock, you cannot do that without an investigation. Best part was when the lady on line asked me if anyone called me regarding the investigation, suppose me being on the line would answer that for her.

It was locked for a few weeks, so I suppose I don't need it if I don't use it much. Please assist me to close my account.
