I have an iPhone 7 Plus and a Macbook Pro 15" 2014. I was trying to make calls from Facetime Audio on Mac from my iPhone. My Apple ID was asked on Facetime on Mac. I entered my details and it told me that your account has been locked due to security reasons. So please enter the answer to your security questions which I don't remember. I entered twice and it greyed out this option of security questions. Now the only thing I was left with was to email myself (through Apple) the reset link so as to reset the password. But here's the bad thing that happened to me: The email that I was using with iCloud and Apple ID was my previous employers email and since I left the job, I couldn't access it anymore. So I couldn't get the reset link. Same thing happened with me on both iOS and Macbook.
Now I can't have iCloud sync between both these devices, can't download anything from the appstores on both the devices. I tried signing out of iCloud on my iPhone (and on Mac) but since my Find my iPhone(Find my Mac on Mac) was ON, it didn't let me sign out. I backed up my iPhone and tried erasing all my iPhone so that I could log in with some new Apple ID but since FInd my iPhone was ON, I couldn't erase my device either. Also tried restoring through iTunes, but all in vain since Find my iPhone was ON.
What should I do now? My Macbook and my iPhone are my primary devices and I can't live without iCloud syncing on.
