Regarding cancellation and bidirectional limited issues: Number and account are two different things. You have to remember that the number is like a mobile phone case of your account, it can be changed back and forth. The reason why your account is canceled or bidirectional limited was because there were too many complaints about your account, so Telegram canceled or bidirectional limited your account. The number is still there, it cannot be canceled and it will always exist.

If your account is canceled by Telegram or bidirectional limited, you can re-bind the number you rented to another account, and you will be charged 10u every time you get the verification code (the random number will also be charged 10u every time you get the verification code). Failure to set an account password resulting in account intrusion is an act of negligence on the part of the customer and the customer shall be responsible for the consequences.
