Claimed that our credit card processing machine needed an "important update".  We haven't used a terminal in over 2 years, and the company that we used would ALWAYS have identified themselves at the beginning of the call.  If I had to guess, they would ask the model number of your machine, then tell you the programming instructions to have it call THEM instead of your normal processor.  They would then start collecting credit card numbers from all of your sales.  Bottom feeders.  Number blocked.

I got a call that went to voicemail at 9:29 in the evening.  I just processed two credit cards, so I was a bit concerned but a little skeptical.  I've spent more time checking out the number than taking it seriously.  I figure they'll call me back if it really is important.

Thanks for your post.  It helped a lot.

No mssg, just a series of beeps.

I got a call with a recording stating that my credit card processing machine needed an "important update". This would be very difficult as I don't even own one.
Scammers!!
