Dear ANDREW HALL,
I am writing this letter to comply with your request that I send you a written statement notifying you and your bank that I lost a total of 25 blank checks that were for my Checking Account.
The account number is 456-8914-2364 and is a joint account with my husband whose complete name is Raymond Earl Smith.
I would also like to request that you send me confirmation that you have completed processing the missing checks and that no payment will be sent out for transactions made using them.
I am looking forward to your immediate response.
