Dear John Stankey, I am writing to formally express my dissatisfaction with AT&T's customer service and to bring to your attention a particular incident involving a manager named Frank. First and foremost, I have experienced ongoing issues with AT&T’s customer service, which I believe is among the worst in the industry. My recent attempts to resolve an internet service issue have been frustrating, as it takes an inordinate amount of time to reach a manager. Frank, in particular, did nothing to assist me and refused to provide his ID when asked. Instead of addressing my concerns, he spoke down to me, as if I were a child, and failed to offer any effective solutions. Moreover, it seems that there is a lack of training in de-escalation techniques for your staff. I urge you to address this issue, as it reflects poorly on the company's commitment to customer satisfaction. This latest incident has only added to my frustration, especially considering it is the third time I’ve had to call for assistance in the three months I’ve been with AT&T. I hope you will take my feedback seriously and work toward improving the customer experience. Thank you for your attention to this matter. Kristina Everitt
