icloud is not working

I am struggling - since the upgrade my icloud is not working properly.

I have calendars, contacts and email which are not updating over the cloud as they were previously.

I appear to have 2 Apple IDs and am unable to get rid of 1 of them which is attached to my icloud account and seems to be a migration from mobileme back in the day 😟

I have tried to update the password on the @me.com but it keeps referring me back to my other apple ID which is working ok.

This is driving me nuts.

So I have tried to back up everything from the cloud to the mac and start again - I can't even get that to work 😟
very frustrated at the moment - can anybody help me out here???
