I signed up for a paid trial of the account to test its bulk upload feature for my company twitter handle. After deciding bulk upload was not a priority at this time, I selected to cancel my paid account upon receiving an email reminder that my trial was ending in a couple of weeks. All good, I got a page saying the cancellation was successful, and my account would update on the last day of the trial period. Then, I get the 'overdue balance' notification. In the complete absence of a reply email or customer service number, I checked the billing page again and I saw to pop-ups: 1. the overdue account 2. that my account was queued to downgrade. Given it was the day my account expired, I figured (after 30 minutes of searching online for answers) it was a glitch in the system and only needed to wait for the downgrade to process. They would not allow me to re-submit 'cancel my account' because of the errored 'overdue' status. Today I go in and see that they did *not* honor my request to cancel the trial and downgrade to free, they bumped me to their middle-tier paid 'professional' account, with a *new* invoice for that plan. Dishonest, poor (no) customer service, lots of redirection prompts to useless company FAQ pages, and an invoice for a service I declined to use or pay for a month ago. Moving back to Buffer if I have the chance.
