I've had about enough of running into people playing online on MW3 and going invisible. Can't kill them or anything. My party and myself have reported this guy and avoided him, not to mention block. We still come across him and it's getting extremely frustrating. This is ridiculous!
I've called twice today, as of 3/29/14 and "Anna" second call was more helpful than the first one. She told me to come here and make a post. I have a gamer-tag written down for one of these players. Please get a hold of me soon.
