This is Peter from the marketing department. I'm here to assist you with this matter.
When a player is eligible for a withdrawal, documents are confirmed, as they were in your case - this is normal for any online casino.
I believe there is a misunderstanding relating to the form you attached to your message here at AskGamblers. When I click it, it doesn't show the entire letter - the borders on either side are slightly cut off. However, the letter is mostly readable and what I see is that you are authorizing your future requests to deposit in the casino, should you choose to do so, to the credit card that you provided.
The casino does not ask for the option to "remove funds from my card anytime and charges are irrevocable" - any charges are from your request to deposit - the context is very important here (ie: deposits to the casino) and they would process through the credit card you provided.
If you still feel this is not the case or something is unclear, you can contact support at suppor[email protected]egascasinoonline.eu or use the Live Chat feature on the site. You have not been banned from speaking to support/security at the casino. That is simply not the case.
