Unable to Redeem Second Code After Buying 2 GPUs

After buying two 1080 GPUs and setting them up in SLI, I am unable to claim my second code for a “free gift” game. After speaking with chat 3 times I was finally told to remove and swap my GPUs so that I can redeem the code. I spend hours making sure everything went into my system the way that I want and now chat wants me to tear it apart to claim my “Gift”?

Is it really unthinkable that someone would buy two cards for an SLI format that you do not support the redeeming of multiple codes?

I really just want to find out if there is a way to redeem my second code without having to tear my system apart.
