Subject: Question regarding a possible billing error

Hello,

I hope you’re doing well.

I’m reaching out because I noticed what appears to be a billing issue on my account related to [service name].

On [date], I was charged [amount], and after reviewing my account details this charge seems different from what I expected based on my current subscription or billing history.

It’s possible that I may be misunderstanding something, so I wanted to contact you to better understand the charge and make sure everything is correct.

Could you please review this transaction and confirm whether the billing was applied correctly?

If the charge was made in error, I would appreciate your help processing a refund or adjusting the billing accordingly.

Thank you very much for your time and assistance.

Kind regards,

[Your name]

Follow-up if they do not offer an alternative

Hello,

Thank you for your response and for reviewing the billing details.

I appreciate the explanation, but I’m still concerned that the charge may not match my current plan or billing agreement.

Would it be possible to review the transaction once more to ensure everything was applied correctly?

If there was any billing mistake, I would greatly appreciate your help correcting it.

Thank you again for your time and assistance.

Kind regards,

[Your name]

Why this letter works

This template helps request a refund when a billing error occurred on your account.

Billing errors can happen for different reasons, such as duplicate charges, incorrect plan pricing, or technical issues during payment processing. When customers report billing mistakes clearly and calmly, companies often review the transaction quickly and issue refunds if the charge was incorrect.

The goal of this message is to explain the situation clearly and request a review of the charge.

For this reason, billing teams usually prioritise investigating these situations and correcting errors when they occur.

A polite message that clearly identifies the issue helps support teams resolve the problem faster.
