Chipotle Mexican Grill

I have been going to this chipotle since I started working right behind there. My coworkers and I always order online, almost everytime our orders are wrong. The attitudes we get from the workers are horrible. I went to corp telling them what was going on but all they did was send free chips and guac. Now let me make this clear. We have never asked for free food, just to make sure our orders are right. I had placed an order yesterday 12/11and went to the location to pick it up, when i went there the additional side sauces were not even prepared and I still received the same attitudes as I typically do. I called 12/12 due to I didn't have time to call on 12/11, the so called manager got on the phone and automatically assumed I wanted free food. I became very upset, my coworker thats' order was wrong got on the phone. He automatically started arguing with her. Stating that we were just looking for free food. She tried explaining everything to him and he kept cutting her off as well as hung up on her. I am tired of this chipotle. And everytime I go in and give them a second chance they roll their eyes and sigh.
