Anyone still waiting for Bioware Store sale items?

When the BW store was having its sale a while back, I took advantage of the prices to get a few clothing items. Three of the four items arrived in a timely manner. The packing slip listed the fourth item as "backordered" (even though that particular size was in stock when I ordered and paid, so their inventory system was trash I guess?)

This was over a month ago, and I have heard nothing about the fourth item. Their contact link takes you to Zendesk, where I left a message almost three weeks ago, with no response (and no indication that anyone even saw it). I saw a few other people commenting on the Twitter post about the temporary store closure, also about missing shipments, so I left a comment there as well. Well, I just went back to check the tweet, and I don't see my reply there. I don't use Twitter usually, so I probably fucked it up somehow.

I'd rather not do a partial chargeback because I do want the item, but if customer service can't even acknowledge my presence, then it doesn't look like I have any other options. Is anyone else in the same boat or know of a better way to contact them?
