I have Koodo prepaid plan for $15. It is said that every base plan includes a voicemail. I got 2 voicemails. Whenever I click voicemail the automatic message comes, 'You can not complete your call. You don't have an active booster and this call is not covered by your base plan'? Why do I hear this? The voicemail has to be covered by every base plan as it is said on your website.
