Half of one of my orders was cancelled.
Yoshi Crafted (Charged full price for)
Kirby Star Allies (Free)
New Super Mario
Tried to work it out with a supervisor on the phone. They told me I could escalate the case, but since I had mixed 2 promotions (B2G2 and CAG16) that I wasn't even supposed to get the games in the first place. He also told me that GS HQ/Corporate cancelled my order for the remaining 2 games, and if I did plan to escalate the case it would be a "waste of time." He told me they would honor the B1G1 (since that what was owed to me) if I had not used multiple promotions.
I tried to see if I could at least get them to do a B1G1 (since I was only charged for half the order), but they would not allow it. At least I was able to get a B1G1 promo. Might just have to deal with that since I'm not sure if it's worth the effort to try to escalate the case.
