This phone number is associated with another Xiaomi Account

Have a Redmi Note 13pro with a chinese ROM.
Tried unlocking but when I log in it says this number is associated with another account
Use another phone number or delete the other account.
I do not have another account.
Have tried looking everywhere.
No luck.
Trying to use mi unlock to flash ROM.

Have found it is not possible to unlock this bootloader. Xiaomi have been totally useless in assisting and have offered no solution. Will sell the phone and buy a proper Samsung. Lesson learned.

Not the ROM is the main issue, in your case the device is.
You should buy Global device instead Chinese one, only Global devices can be unlocked by the users from outside China.
