Not Max, we don't have any mail, in any folder. When we had paid the $225 we received a mail (or two), and it was not spam, and we received the emails of support, and they are not spam, and we receive emails from Exadel announcing how wonderful is the company, and they are not received as spam.
We've had a unfortunate issue with a credit card and other vendors (like Pushwoosh and others really wonderful companies) have warned us and have helped us, all of them, and none of them have taken advantage of this situation for collect more money, except Appery.IO, which canceled our account quickly for collect more money.
You have your $225, we have our projects. That's all.
I do not wish to discuss this further, It has been a unexpected and unpleasant surprise for us. (Further up on the road.....)
Thanks again to the Appery support team, is great !!, we understand that these are Exadel or Appery.IO business matters or business afairs.
