Masterpass Automated Security Glitch Prevents Users From Adding New Bank Cards

I am unable to add new cards to my Masterpass account. Although I tried 2–3 different bank cards, the system refuses to let me add them, displaying an error warning that states "crime detected due to consecutive deletions." Because there is no direct customer support channel or contact option available for Masterpass, I cannot resolve this issue on my own or obtain any explanation. Despite having no fraudulent intent whatsoever, this automated block has rendered Masterpass completely unusable for me.

I demand that the card-addition block on my Masterpass account be lifted, that necessary account checks be conducted, and that my account functionality be fully restored. Additionally, even before this block occurred, when I successfully added a card designated as "Silver," the discounts applicable to Silver cards failed to display on the merchant's website.
