Quick Template (Short)
Hi [[NAME]], I'm writing about the unresolved issue from my call on [[DATE]] (Ref: [[REFERENCE]]). Your team's lack of follow-up and dismissive attitude has left me deeply disappointed. I expect a resolution and a call back from a manager by EOD tomorrow. [[YOUR_NAME]]
Formal Version
Dear [[NAME]], I am writing to formally document my dissatisfaction with the customer service I received on [[DATE]], reference number [[REFERENCE]]. Despite multiple promises, my issue remains unresolved, and the tone of the last interaction was unprofessional. I request an immediate review, a written apology, and a concrete resolution plan within 48 hours. Sincerely, [[YOUR_NAME]]
Friendly Version
Hi there [[NAME]], hope you're well. I'm following up on my recent experience with your support team (ref: [[REFERENCE]])—it really fell short of the great service I usually hear about. The agent seemed rushed and didn't solve my problem, which was about [briefly state issue, e.g., 'the faulty part']. Could you please take a look and help get this sorted? Thanks so much, [[YOUR_NAME]]
Firm Version
[[NAME]], this is a final follow-up regarding case [[REFERENCE]]. After 7 days and three unreturned calls, the initial poor service has now become a failure of your escalation process. I am escalating this to your supervisor. I require a substantive response with a resolution offer by 5 PM tomorrow, or I will be forced to pursue all available consumer protection channels. [[YOUR_NAME]]
