You don't make it clear if this is a civil or criminal matter. It appears you have been served with the complaint. If you can't answer or otherwise appear in the time required you normally need to file a motion and have the court approve an extension.
Please speak with a local attorney as this is not something you should do without legal advice.

You need an attorney NOW. These are serious charges and I am guessing a bench warrant is out for failure to appear
The law office of Anders Ferrington 601-316-8428 practices state wide. In no way am I offering you legal advice, and in no way has my comment created an attorney-client relationship. You are not to rely upon my note above in any way, but instead need to sit down with counsel and share all relevant facts before receiving fully-informed legal advice.
