Note that we are not authorized to remove activation lock from any device. And, the presence of activation lock usually means that Apple support will not be able to help you. That is, under your circumstances, Apple support usually will not remove activation lock unless you can provide proof of ownership that they will consider to be sufficient. In this case, you would need and have your purchase receipt for the device from an authorized Apple seller with the device's serial number on it.* You also would need to present a photo ID. But, Apple support is open minded. So, given that you insist that your are "sure 100% that the apple id and password are correct," you can contact Apple support for help using 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.
