KFC review: Nacho fries... Tacos... No slaw

First of all, I never received my 10.00 coupon from kfc from terrible food about 3 months ago! My son wanted tacos. Went there tonight. Card machine wasn't working, and had no slaw. I ordered 3 tacos with 1 lettuce and tomato on side, and nacho fries. They came out at different times. The fries were horrid, and I got a refund right then. Got home and had three taco supremes. My son doesn't eat sour cream! This is the worst kfc I have ever went to. I live 15 minutes away and did not feel like driving back. I want a refund. Again, the last time was never resolved. I am not going back. Please refund me. Maybe if coupon, i'll go back, but i'm not spending money there anymore.
