caller id blocked; no message

Called at 6:30 am left no message

This was verizon wireless tier 2 support, calling to help with a ticket i opened.  they left a message.

called my cell phone at 1130 PM  on Oct 3, 2013 and left no message, when I called back a message came on that said "Thank you for calling Verizon Wireless, please dial 800..blah blah blah for customer service. I tried it from my house phone too, same recording!

This number is infact from Verizon Wireless tech support.... I get return calls from them on this line. Maybe they are miss dialing return calls.
