Yeah when I was on Republic Wireless I'd sometimes get calls from people who had called the "secret" number because it had been recycled. I used to get calls from the county clerk's office reminding me of my upcoming court dates and probation appointments. I called them back and said you must have a wrong number, they checked and of course had no record of my phone number on any of their records and could not understand why I was getting these calls, nor could they figure out who should have been getting them. Later I realized that someone must have had that "secret" number recently and it had been recycled into Republic's pool.
