406-426-3362

I don't recognize the number and they never leave a message.

Rec'd call from "Debt Relief Services" - an automated voice asks you if you want more information. They also call from 701.661.1006. Don't bother asking a real person to take your number off their call list - they will just hang-up on you. Instead, after you hang-up, dial *69 and the phone provider should tell you the number that last called you. Call that number - you should hear an automated message asking you to push a keypad key to have them stop calling you by adding your number to their do not call list.

But, you may discover as i did that they just keep calling but from a different number.

i've requested three times not to be called (hit #2) and they continue calling my mobile

Says 'Touch Plan' but when you dial the number back it never connects.  I got this call right after I got one from 714-505-1791 (U SA Photo Copy Service) saying my debit card had been deactivated, blah blah blah and press 1 to reactivate it.  I called and left a message saying they were scamming and I would report it.  Then I got the second call from 'touch plan'....whose number does not dial up.

Recorded message asking whether I want to be part of Google's 411 directory. Thought I'd bite, so I pressed 1. It said I was being connected to a live operator. Someone picked up and hung up on me. Pretty sure this is a scam.

Call all the time never a message, just keep calling, don't answer like to hang up.
