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.
On your terms and conditions page, you have not mentioned the deletion of a card you have mentioned blocking a card. And it is for 5 declined but you have charged me 6 times for the decline. Why you have charged 6 times instead of blocking after the 5 declined and why there is no notification about the charge as well as about the deletion of the card?
