Hello, thanks for taking the time to contact us today. Sorry to hear about the freezes, that certainly sounds frustrating! You are seeing this every game? Are you using a wireless connection? Would it be possible to try your disc on a friends console, or try a friends disc on your console? Sometimes even pristine looking discs can cause problems.
Since this issue happens online, have you tried to power cycle your router? Also, try to use
different account. Run the disc to diff. console and run another BO2 disc on your console. It helps to know if it is a disc or console concern that needs to be addressed.
