Temporary Locked Instagram - Can't access the email attached to the account.

Hi All,

Appreciate any help! So I had the follow/unfollow app on Instagram and my account was temporary locked due to me using this. I now need to just follow simple instructions to get the account unlocked - the first being a code sent to the email the account is registered to. The problem being this account was made years ago and someone my email is registered wrong... it's co.uk but my email is .com ... I have emailed Instagram and just get told to use the help centre. This isn't a generic problem and I have no idea how to resolve it.
