Even though the card has been cancelled, it is still connected to your bank account and the funds should arrive successfully into your bank. You may read the steps in our article: How do I withdraw funds?
Due to the regulatory requirement that AvaTrade operates under; we have strict AML (Anti Money Laundering) guidelines.
