New MacBook Pro slow performance, battery not working

I have a very recent (mid-2014) MacBook Pro Retina 15" that has been working fine since I got it (about two months).

Suddenly, it has begun to run very slow in all apps, even though CPU usage is very low, and it does not seem to be under stress.

Additionally;

• The battery is not charging, The battery is stuck at 22%.
• If i disconnect the charger, it completely dies immediately. After restart, date and time is reset to 1st january 2014 0:00
• The battery status is "Replace now" even though it should be almost brand new

I've tried these things, which did not help:

• Restart
• Shutdown/start
• SMC reset as per http://support.apple.com/kb/ht3964
• PRAM reset as per http://support.apple.com/kb/PH14222
