I create a facebook account and then created a page for my business with that facebook account.**but after few minutes facebook disabled my facebook account and asked me for identity verification I submitted all the documents that are needed for verification. **but nothing happened after that I created a facebook account with the same number again and this time facebook created a new facebook account for me with the same number again but when I created that page again they did not allow me to use the username that I used previously.**after this, I deleted that account and waited for a month for the deletion process.*now that account is completely deleted but when I am trying to create a page and using that username a message is appearing that "this username is taken. try another one.**what can I do now please tell me I want that username back.
