We have certain rules established by the bank, which are clearly stated in this thread (
https://bitcointalk.org/index.php?topic=5484771.msg63647081#msg63647081), on our terms and conditions page, and through periodic notifications on our website. These notifications serve as a reminder that multiple declines due to insufficient funds may result in your card being deleted. Your card received a significant number of declines for insufficient funds and was therefore deleted by the bank’s risk control system.
Where have you mentioned the deletion of the card if you have mentioned anything about the deletion of the card then show it in an archive (I have asked for the archive as you can blur it). For decline, you can block my card but you can't delete my card as delete has not been mentioned. Note: I have got the card for free as a trial that doesn't mean you can delete my card. And I will soon publish howto treat on your customer service on telegram. Also, I have to write a few more information about your service as well as customer service.
