I recently requested the cancellation of my Platinum Charge Card due to the uncertainty of its limit and asked for a refund of my joining benefits. Consequently, they canceled my card and debited the 100,000 points joining bonus. I received an email confirming the cancellation, and it was reflected in my Amex app. My question is: Is there any possibility of facing issues later on, such as having to pay the outstanding joining fee or other amounts? Currently outstanding shows 70790 that equal to joining fee.
