How to recover message deleted by mistake!

If you deleted the message shortly after you received it (before you made a backup), the message is probably lost for good. If the message was included as part of your backup, then restore that backup:

Be aware that restore is an all or nothing process. You cannot restore only messages (for example) and any information on your device between now and when the backup was made will be lost.

I received a message from a Craig’s List customer and deleted it by mistak. Can I recover this and if so, how. If possible could ATT store or Apple store help me?

You would need to restore from your icloud or itunes backup, assuming that text message was part of the backup, if not there is no way to recover it.

You can restore from a backup as long as the backup was not made after you deleted the text message. If you have backed up since you deleted the message, I'm afraid it's gone.
