Doc 分享了一则关卡 DP。目前似乎被关卡的人不多（这卡持卡人数量本身也比较少）。关卡来自 Fraud Risk Control Department，信件信息如下：
The credit card contract applicable to your account grants either party the right to terminate the account relationship or the credit privileges at any time with or without cause. It is a voluntary agreement that either party may terminate unilaterally.
The Bank has chosen to exercise said contractual right and hereby informs you that the above mentioned account will be close effective <date>. Please destroy and discard any card you may have received for this account.
Credit card #XXXX
After said date, you will not have access to any of your credit card benefits. As a result, you must take the necessary steps and make the necessary arrangements to avoid setbacks. If you have authorized any companies to charge your account for membership fees for ongoing services, please contact them directly to arrange an alternate method of payment.
If there is a balance on the account, you will continue to receive your monthly billing statements. We inform you that you remain responsible for the payment of any balance in the account, which will remain subject to all the terms and conditions of the Agreement.
