Hello @mc-spike, I hope you are doing well. The contact deletion time is directly proportionate to the attachments, tickets and other date associated with the user profile. If the intention is to convert a contact to  an agent, you can simply use the button in the contact profile : 

In this case, let’s have a ticket created on your behalf to check this further :) Thanks! 

Hello @mc-spike, We’ve restored the contact from the backend with the help of our developers. I’ve dropped a mail to you regarding this as well. You should now be able to convert the contact to an agent. 

Let us know if you need any further help with this. Thanks :)
