Yesterday, my husband ordered a grilled chicken sandwich from Chic-fil-a, the bread on the sandwich tasted stale, so he placed a call stating his dissatisfaction of the sandwich and was told to return and the sandwich would be replaced. Now today, he returns and repeat what was told to him about the replacement of his sandwich. He was told there was no record of the call. After speaking with the shift manager my husband began to call the corporate customer service line to file a complaint. It appeared the drive-thru line was beginning to back up and instead of the General Manger (Kevin O'Leary) coming to the window to descalate the situation, he instead esculated it, threatening to call law enforcement. I currently have stage 4 heart failure and me and my husband dine frequently at this particular Chic-fil-a. To be treated in the manner the general manager displayed, cause me to experience heart palpitations and I became light-headed, I felt it was mostly because of our race, we were treated that way. I have recording of the incident and I plan to share with social media, so people can see that hourly employees are not the only employees that need customer service and diversity training.
