Recovering Azure Account

Our company Azure account was managed by our previous IT Administration sub contractor and we need access to the account. Unfortunately, any attempt to log into the account has failed.

We have redirected the emails to my in box and have requested a password reset but I get a message 'password reset isn't turned on for your account'.

I have reached out to our new IT Admin team in hope they can do something to help, but failing that, is there any other way we can either recover the account or end the account and start a new one?

Thanks,

Chris F
