I listened to the pre-recorded message to find out if they'd leave a name or any other identifier. Nothing. At the end of the recording, the instruction is to press 1 if you want a call back or 9 if you wish to receive no more calls. Since I didn't pick up and wouldn't have listened to the entire message, the instructions wouldn't help. The message itself is about using their credit card processing services for my business (which I don't have). Very annoying to get these calls at early hours.
