Blizzard 6 months reward

This recently happened to me, I always renew with a six month sub because I love playing Classic. Blizzard mailed me a gift in retail for renewing my six my sub. The jokes on me because I renewed my sub to continue playing classic. But they mailed me a gift in retail and I’ve never even logged into retail. I’m confused as to why they even bothered giving me a gift since I’ve never even logged into retail. If I renew my sub and I only log into TBC Classic why wouldn’t you give me a gift there? Seems like a missed opportunity, and I’m left feeling like I was giving a thoughtless gift that has no meaning or application to me.

TLDR If I’m renewing to play Classic you should give me a gift for Classic, not for Retail, otherwise it comes off as you don’t even know your player base and somewhat tone deaf (eg gifting them gifts for other Battlenet clients).
