Stalled Complaint — No Response After Weeks

Problem/Feature Description

Six weeks ago, Priya Nair (Delta Diamond Medallion, 7-year customer, 1.1M lifetime miles) sent a well-crafted complaint letter to Delta after her business-class flight from New York to London was cancelled with less than 3 hours' notice. She had to purchase a last-minute replacement ticket on a competitor for $2,800 and missed the first day of an important conference. Her original letter was sent directly to Delta's general customer service email and asked for reimbursement of the replacement ticket and a meaningful miles credit.

Forty-two days have passed and Priya has received only an automated acknowledgment. She is frustrated and ready to escalate. She wants to know every lever she can pull and is prepared to be aggressive — she has mentioned she is thinking about threatening to sue Delta if they don't respond.
