Thank you for your opinion. BMTMicro I also wrote a letter, but they forwarded it to the developers 3dxchat. A warning about the automatic subscription renewal should be in the agreement, but it is not there.
The link no cancellation automatic cancellation of subscriptions and removal of credit card data. I checked all the sections before you write on the forum. From the developers, I also no answer.
Why do I automatically renew the subscription? Deducted money from my credit card? I wasn't planning on renewing this month! Where are stored my credit card details???
