They charge you on the spot no 30 day free trial offer... that's called bait and switch from where I come from
Thanks for your review. I'm sorry for your experience but this was not the first time you activated the Koongo app. Based on our records, the first app trial activation for your Shopify store was done in May 2016. So, the trial period was already expired in Feb 2019. I can offer you the payment refund and reactivation of your trial period, so you'd be able to test Koongo again. Please contact me at firstname.lastname@example.org for more information.
Based on your experience, we implemented a free trial reset. Koongo free trial is reset after one year of the account inactivity. So, it should not happen again.
