Unfortunately I don't have the time to correct this text now.
However, I would like to give you some advice.
You must learn the active and passive usage.
An account cannot close itself.
It gets closed by someone.
So you cannot say:
Our account has closed.
You can only say:
Our account has been closed.
Depending on the tense you can also write it like that:
Our account was closed.
Our account had been closed.
I have closed the account. -> The account has been closed (by me).
I closed the account. -> The account was closed (by me).
I had closed the account. -> The account had been closed (by me).
