Congratulations, allow me to be the first to congratulate you on solving a difficult problem that deserves to be celebrated.

The complex story of canceling your card reminds me of government transactions in the third world. In my country, for example, when you want to submit a request to a government department to solve a problem, they enter you into a maze of complications and official government papers that you are forced to submit.
Where you end up with a pile of worn-out official papers and are eventually forced to abandon your application without solving the problem.

But the good thing about your story is that the problem was finally resolved after all this delay. It is shameful for an exchange that describes itself as global to have all this delay and complexity occur, as this will certainly affect its reputation negatively.
