Dear :

As part of our efforts to improve our services, we have decided to extend the hours for our service in order to meet our customers' needs. We are now open from a.m. to p.m. Monday to Friday, a.m. to p.m. on Saturday, and a.m. to p.m. on Sunday.

We hope you will benefit from our longer hours.

Sincerely yours,
