Online voucher-less

The use of their online services to purchase gift vouchers for others is poorly executed. The process of purchasing the voucher is smooth and easy, and a swift response to said purchases is great. However, the actually emailing of the voucher the recipient is terrible. I have had three separate occasions where the voucher number was never sent, only online proof of purchase. Even with this in hand, the stores themselves can not verify the voucher and I have had to hunt down someone who can help. It seems a bit ridiculous that after purchasing an online voucher, the voucher is never emailed and that the stores don't have access to these purchases to confirm the number and process while i stand in front of them.
