Is it (super clueless) to ask the manufacturer for a shipping date??????

I participated in an app where you get coupons for completing tasks. I didn't redeem them at first, but later my helper reminded me that I could, so I thanked them and redeemed an electronic gift voucher about half a month later. It's been almost a month now, and I just asked the staff if the voucher was ready. The staff said it wasn't, and that we have to wait for the manufacturer's shipment. I just casually asked out of curiosity if the manufacturer had given a shipping date, and today the staff called me (super clueless). So, is this something I'm not allowed to ask? Am I clueless for asking?? What do you guys think?
