Moe's Southwest Grill review: burrito bowl

I came in for my birthday dinner on 10/29/2019, around 6pm. There were 3 people working at the time, and my husband and I were treated poorly. Which isn't the complaint I have, my burrito bowl had a piece of hair, which is disgusting enough but again I really wanted my food so I tried to finish it - then I ate a piece of plastic. I have complained to them in the past and they laughed at me and made fun of me, so I threw out my food and left... I would like a refund please, at the very least I would like my free birthday burrito coupon refunded.
