Hi there,

I received a letter from my bank, and I have some questions about it.

We refer to your letter of September 30, about the matte of the missing cheque.

To date, we have not traced it, although we are usually very efficient when dealing with incoming remittances.

So, to set our records straight, we would be grateful if you would settle this account as soon as possible, as it has remained outstanding for two months now.

We look forward to hearing from you shortly.

I don't understand why the writer put down 'to set our records straight' which means 'to write or say something in order to make the true facts known'.

Thanks in advance

To set our records straight = to correct or confirm the bank's record-keeping. They want you to come and pay the outstanding amount, Simon. They cannot find any missing cheque.
