Some sort of telemarketer - a callback to the number gives the message "...Press one if you want to be placed on our 'do not call' list..."
As a Business we get these telemarketing calls from time to time. At least this time the agent took time out to say, "Sorry, wrong number."

Caller ID shows CUSTOMER SUPPORT.
They don't leave a message.  Have called several times.  

I see postings here where folks have pressed the buttons, like "1" to be removed from the list.  Please be careful when doing that.  They ran a report on local news about how pressing numbers on your key pad can provide access to the calling party to use your phone number from wherever they are.

I am glad I am not alone, these calls have been driving me crazy. "Sorry Wrng number" while hangin up other line is ringing "sorry wrong number". Thank goodness I only get these call s at the office at not at home!

Started 5/19/09 repeated calls to our company within seconds of eachother since we have a multi line system.  Recorded message states "sorry wrong number!" and hangs up.  5/19 we counted 17 calls in a 6 hr period, 5/20 we stoppws counting after 12 calls and so far since 8:11 a.m. to 10:15 this morning alreadt 6 calls to us.  Total annoyance...waste of co. time...very frustrating........

stupid idiot from a supposed customer support keeps calling.

did a reverse look up and it came from a home in camp pendleton.
