Unlisted number problem

[brgrundy]

I have an unlisted/blocked number.  Fido apparently set it up so that all calls should show unknown in the recipients call display.  I have had occassion to contact companies with call back systems and those systems somehow know my number.  How can that be?  What can I do to ensure my number is blocked to those systems as well until such time as I provide the number?  Thanks,  B.

Hey @brgrundy ! 

We do everything we can to make sure that the Call Display Block works and that your privacy is protected.

With the restriction we add, your name and number will not show when you place an outgoing call.

However, some callback systems may still be able to trace back the call without seeing the number itself.

Hope this helps!
