David in Kansas City

I like my local gaming store. Don't think it's fair to bother them with refund request since it was 343 that knowingly sold an unfinished product. After one week with no fix in sight feel like I've waited long enough, any way I can return the disc and get a refund directly from 343 Industries? Also anyone else annoyed as hell about all the ads they are still running for this essentially broken game? (Yeah campaign works just fine but MP is about 50 percent of the reason I purchased this, so yes, broken)
