Somehow, I received a short message from Gitzo, which was overdue, so I paid attention to what happened in the official account of WeChat.

1. It may be that the Gitzo loans overdue of the former card owner did not return it, and the Gitzo account of the former card owner was not untied before abandoning the card, but you just changed the number and bought this calling card, so the information will be sent to your card. 2. Your identity information was leaked. Someone used your identity information to get a loan from Gitzo and left your phone number. Gitzo will send you a message to collect debts. If the above two situations are not true, then don't care. Set this dunning phone number to the blacklist, and you won't be disturbed again.
