Why you have closed your previous real account? I actually don't understand why people close their account, if you want a break or not want to continue this, what is the need to deactivate? you can simple set your availability to out of office.
Now, if you have really deactivated your account then from which account you are using this platform to communicate?
If you have really deactivated your previous account and want to come back again, I suggest you to create your account with your original details and just after the creation, do contact customer support, send them a request and explain your deactivation reason, and share what they will ask. This is all I can suggest as if they can allow you, you will have the evidence in future incase of any problem you face as all the chat will be send to you in the email. Also you will have the closed ticket in customer support page.
Without doing this, you will have no any guarantee and your account can be ban anytime if they think so.
