yesterday I have started the game and I have seen that my blackops online level is 0 all of my scores(prestiges also) had gone. I was prestige 10 and level 34. What can be the problem here and how can I get back my scores?
I have contacted to Activison Support and they've sent this respnse.
Thank you for contacting Activision! Sounds like you have a network communication failure with the servers. Any sort of interrupted communication that occurs when the game is processing or updating stats can result in a reset or rollback; It's generally due to factors beyond your control. The servers will have to work to retrieve your stats, and this may take some time. This is no estimated time for the retrieval.
Now my prestiges are back :)
