AppleID suspended. Need simple Restoration process.

Received an email stating AppleID has been suspended due to some suspicious activity of trying to log in from a different Geographical location.

First of what does an "account suspended" mean? I'm able to login and use it as usual and couldn't find what's different.

When I tried verifying my AppleID, the process was too tedious. Asked for address, card details, security questions all over again. Couldn't able to complete the process as the form submission was not accepted. Please provide an easier way for restoration. It's very irritating that I couldn't contact Apple regarding this via email.
