iCloud on iOS devises not working
Hi All
I had my apple id email account hacked and noticed some unusual purchases on my credit card from iTunes. I have changed the apple id and password on my iMac but now iCloud is not working on my iPhones, iPads and apple TV. I have just read that I needed to sign out of iCloud on each device first but now I can't sign out as the password to the original account or the new account details are not working.
I am at a loss as to what to do. My iMac works fine but there is no server access from any of my other devices.
Please help!
iPhone 5s, iOS 7.1.2, other apple devices
