How to enable a disabled iPhone 6plus

iPhone locked and disabled after several incorrect password and Apple ID entries. Called support, not much help.. Went to ICloud.com and removed the phone and tried to erase. Nothing will take place till phone is connected back on the Internet. Can't enable to connect. What do we for? Paying for s phone and can't use. Last iCloud backup was 2 days ago, so I just need to restore, phone will not connect to ITunes
