Subject: Urgent: Unresolved Billing Issue on Account [[Account #]] - Second Attempt
Hi there,
I am writing again to resolve a persistent issue with my account, [[Account #]]. This is my second time contacting support regarding this problem, as my initial ticket [[Ticket #, if you have one]] from [[Date]] has not been resolved.
On [[Date of charge]], my account was incorrectly billed for [[$Amount]]. This charge is for [[briefly explain the issue, e.g., unused parallel tests I was assured would be credited, a charge after I downgraded my plan, etc.]]. Frankly, having to chase this down and spend my time verifying my invoice has been incredibly frustrating and is impacting my team's budget planning.
To resolve this, I require you to issue a full refund of [[$Amount]] to my original payment method immediately. Please also confirm in writing that the issue has been corrected on my account to prevent it from happening again.
If I do not receive a satisfactory response and confirmation of the refund within 48 hours, my next step will be to file a formal complaint with the Better Business Bureau and initiate a chargeback with my credit card provider.
Thank you for your prompt attention to this matter.
[[Your Name]]
