If the Order that you received was entered by the court, then it's official. You can tell if it has the judge's signature or stamp on it. If, on the other hand, it's attached to the motion as an exhibit (a "proposed order"), then it's just what the credit card company is asking the court to enter. As jespah
notes, without seeing the documents, it's not possible to determine what you're dealing with.
You can agree to the request, but you don't have to. The court can (and usually does) grant a request for an extension of time on routine matters unless the requesting party (the "movant") is seeking the extension for purposes of delay.
