Hello Anongnat,
As your Sales Area Manager for Tableau, I am sorry if we never connected on phone. As a result, I am preparing to offer you one of three things:
1) I will extend your trial beyond the typical 14 days given so that you have more time to explore tableau
2) I will be inviting you for our Free Tableau Introductory Hands on session
3) Close your file and not disturb you again.
I’m hoping you choose option 1 or 2, I can also have a short call with you if you are free this week to help you on Tableau
