NPC International Pizza Hut Online pizza ordering visa checkout Oregon city - online order Internet

 I had an order including delivery fee totaling 14.99. I entered my card information and I receive instant text alerts when my card is charged. I wa charged 17.99. I called the store and they said they show I was charged 14.99 and to call customer service. I've been on hold so long I'm expecting my pizza now any minute. I would like to speak with someone to make sure this charge gets adjusted but the store says they have no control over online payments. Their customer service center is impossible to get a hold of. If they are charging every so many customers a few dollars extra, that money adds up. I'd like to know who is responsible for this charge, when it is processed online and the store has no control over what is being charged? I know it's only a couple dollars. But I make 9 dollars an hour and can't afford to lose a few dollars here and there. What's going on here. It's not a tip, or delivery charge. And their store shows a completely different amount then the amount my transaction my card company showed instantly after the transaction was processed.
