Someone else might be using your account message, cant access my emails

I have the message It looks like someone else might be using your account and have attempted numerous verification forms without success when trying to log into my main email address. I have tried to reset password and still cannot enable it again. !  I know i have put all the correct information into the boxes and had no joy and i really need to get into my emails. I have requested help from the support team and have received an email witch a link to check the status but when i click that link it says - the sign in name that you are using does not match the primary name that was used to create the support request.
