Subway review: 6 inch sub

My granddaughter got 2 /6 inch subs only, she said it was $14, I called the restaurant, and asked why it cost that much, the very rude person said on one of them was guacamole and the other was pepperoni, they should have been told that it would cost extra. They didn't even get any veggies, I saw the sub it was just few bites. I told her to not ever go there again, that was ridiculous to pay that much. Our subway in Hamburg, AR will not accept the offers that are text to my phone. Please someone straighten this place out. We love subway, but can't afford to eat at this one. We are a small town with very limited places to eat. Other people have been complaining about them too. I'm sure they are loosing business!
