I posted on this forum before about bad behavior by Fanatics, the company running the Blizzard gear store, and nobody connected to Blizzard on this forum cares (or cared to answer).
Sure, Fanatics might be besmirching the Blizzard brand - not that Blizzard’s handling of the gear store was much better when they still ran it - and Fanatics staff was downright rude, abrasive and did not care one bit about delivery times or orders not being sent out; but it’s no longer a Blizzard-ran operation, they just license out the name and merchandise.
Sorry to say but I think that if you can’t contact them with the means available on their website, it was my experience in my last post that no blue poster on this forum will care and I concur with the poster above that you should open a dispute with your credit card company (or with Paypal, which I found is more helpful in these situations than people give them credit for).
