joy Hello,
Keep in mind, credit is for Xiaomi Flashing only,
This service is not for unlock bootloader or clear mi account, there are another service for that.
To remove FRP, you only need 3 credit for Identify Device, after that you can clear FRP via special task, or by manually erase FRP/Config partitions. After this operations, FRP will be clean.
But not for micloud service.
For micloud, there ane another service called [Xiaomi] Unbind Mi Account, unfortunately this service available at Indonesia regions only.
