Response to an improper billing after settlement

AFTER SENDING OF YOUR ARES REGULATION BILL

Mr [CONTACT name],

On [DATE], I received your letter notifying me that I had a balance by an amount of [amount].

[DATE] I sent you a cheque for an amount of [amount]. You should have received our check before writing this letter and as such, I am embarrassed.

In case you have not received my check at the time of the receipt of this letter, I would ask you to inform me that I have a ban on cashing in on the cheque.

I remain waiting for your news.

Receive, dear Sir/Madam, my best regards.

The Director-General
