Review:I tried to explore Tableau to learn data visualization — but without clear warnings, I was redirected into creating a Salesforce account and got unknowingly enrolled in a paid subscription.As someone new to the platform, I had no idea that Tableau and Salesforce shared accounts or billing systems, and I never agreed to any paid service. I reached out immediately to cancel, but both Tableau and Salesforce ignored my requests until I was eventually billed $120 — for a service I never used.This was my first interaction with Tableau and it left a terrible impression. The experience felt misleading, unfair, and designed to trap new users into subscriptions they don't even realize they’ve started. I’ve since deleted my account and will never return.If you’re new and trying to learn Tableau, be very careful — what looks like a free educational trial could secretly activate a Salesforce contract.
