The same issue, I am being charged for PRO but my account got downgraded to FREE. I have contacted chatbot twice, was promised a refund and feedback from support. Two weeks have passed, none of that happened. Did anyone get help with this issue?
UPDATE: It seems that they do not send any email notifications whenever something happens with the subscription. In my case it was apparently insufficient funds to cover the fee. I had no idea that happened, I got no notification relating subscription downgrade due to the payment issue.
Regarding chatbot - the same problem. They posted answer after several hours, when I was logged out. No email regarding their answer in chatbot.
