Taco Bell

I have never submitted an online complaint in my life but my experience at this Taco Bell was so bad I just need to do this. I ordered a Fiesta Taco Salad and the shell which is usually my favorite part tasted like it was sprayed with disinfection chemicals. I had 4 people in our office taste it just to be sure and they said yes it was awful and did taste very much like chemicals. I threw the whole thing away. also we were shorted 3 items and even given nacho sauce without our nacho chips. when I tried to call the store and voice my concern I got a voice recording saying" mailbox not set up". I tried calling 3 other times to only get the same voice recording. I just hope that I do not get ill from eating a part of that disgusting salad shell. If I do I will pursue this complaint much further.
