Why was I charged $248.70 during my Auto DS trial period?

I installed the auto ds into my Shopify store , I started a 14 day trial but then was charged $248.70 so I was charged when I wasnt supposed to.

Stay away from this company. I’m currently in a dispute with them via Paypal. They also charged me while I was in a trial period.

Hi, there! If you’ve selected a plan and started selling during your free trial period, it is expected that you will incur charges, potentially including transaction fees and third-party app fees. If you’re not sure what the charges are for, you can view a breakdown of your bill and contact the app developer for further support if you still have questions.
