If you really want your rewards points and are worried about getting screamed at for not using your GTC, and you can afford to wait a little longer to get you money, just do this. Use your own card for everything, but have DTS pay all your expenses to your GTC. When your voucher gets paid, log onto your Citibank account and your card will have a negative balance; just click on request a refund and a couple days later the same amount of money will get deposited in your bank account. If finance is looking beyond your voucher at your actual Citibank card activity then maybe you're out of luck! Sent from my SM-G965U using Tapatalk
