Quick Template (Short)

Hi [[NAME]], I'm writing regarding my recent experience with your service (Ref: [[REFERENCE]]). The support I received was unhelpful and did not resolve my issue. I expect a resolution and an apology by [specific date]. Sincerely, [[YOUR_NAME]].

Formal Version

Dear [[NAME]], I am writing to formally express my dissatisfaction with the customer service I received on [date] regarding case [[REFERENCE]]. The representative was dismissive and failed to address the core problem of [specific issue]. This falls short of the standard I expect from your company.

Friendly Version

Hey [[NAME]], hope you're well. I wanted to share some feedback about my recent support interaction about [[REFERENCE]].

Could you look into what happened and help me get this sorted? Thanks so much, [[YOUR_NAME]].

Firm Version

[[NAME]], this is a follow-up regarding my unresolved complaint (Ref: [[REFERENCE]]). My initial contact on [date] with your team was unsatisfactory and the promised follow-up never occurred. This is now a second failure in service. I require escalation to a manager immediately and a binding resolution by [specific date + 2 days]. If this is not achieved, I will be forced to pursue all available consumer protection avenues. [[YOUR_NAME]].

A: Provide the date, time, and specific issue details. The company should be able to trace the interaction from your account.
