Given your circumstances, there is no way to get your account back unless you have an extenuating circumstance (e.g., you have your purchase receipt for a pertinent device from an authorized Apple seller with the device’s serial number on it). If you want to contact Apple support to discuss any possible extenuating circumstance, see the support options below. Alternatively, if an Apple Store is open in your area, then you can go there to deal with your problem. In this case, you can make a genius-bar appointment (https://www.apple.com/retail/geniusbar/) if you want.
