Roblox Account Blocking

My daughter's account has been blocked. The only option is to provide your email address or phone number. When my daughter set up an account, she was not required to provide this data. When she used the account, she was also not asked to enter her email address or phone number. Now that the account is blocked, I wrote to support for help. They replied that in order for the account to be unblocked, I must provide an e-mail address or telephone number, which was not required before. I was suggested to set up a new account for my daughter. She said no because she had a lot of things bought there. Otherwise they won't help me. I didn't buy Robux for her. Only by king.... What should I do next to recover my daughter's account?
