Your (name) Service Agreement has expired
for the equipment that we installed on your premises.
We have not received a remittance or a reply to our

the mail.

If you have not sent us your payment, please forward
your remittance within ten days, or we will assume you
do not wish to continue your Service Agreement.

Should you decide to terminate your Service Agreement, we
will look forward to furnishing the same high quality
service on your (name) equipment at our currently
hourly rate of (amount) per hour, plus parts and
travel expense.

If payment has been made or if there are any questions in
regard to your account, please contact me at (213) 555-7074.
