Dear John Harrison,
We received the check you sent for the amount of $500 as advanced payment for the office rent. However, as stipulated in the contract that we both signed, you also need to send me an additional $100 dollars for the utilities. Please go through the terms and conditions we agreed upon, as this can probably clear this issue up for you.
I would appreciate it if you could send me the balance before the week is done. If you have any further concerns, you can reach me through my office number, which is 333-3333 or send me an email. Thank you.
