Taco Bell

I went through the drive thru this evening to get my family's supper. I ordered 2 spicy tostadas for myself. We took the food home to eat, and neither spicy tostada had the special spicy sauce. That sauce is the whole point of those things. I looked on my receipt for contact/ survey info. The top of the receipt had a survey code, and said "for a chance to win, see the back of the receipt." I flipped it over, but the back was blank. What good is a code? So then I called the store, but didn't get an answer (this was around 10pm and they're open till 2am). I would very much appreciate someone getting back to me. I would've driven back, but it's the next town over and extremely inconvenient when I have to get my kids in bed. Thank you,
