That's a significant amount. But has it already matured or surpassed the 6-month or 180-day lock-up period? That's basically one of the conditions of staked CRO to be withdrawn, right?
CRO was staked to maintain the card active. After about 24 hours I was replied by their app's support through chat and they initiated the cancelling process. Just received a new message this morning confirming the card was finally cancelled, so I unstaked the CRO immediately and sold it.
After more than 1 month the request is finally solved!
