Dear Joseph Hall,
Last May 2, we sent a billing statement to your office for the month of April. It was received by your receptionist. However, as we have not heard any news, we would just like to confirm if you have received it. Please let us know by giving us a call at 434-3434. Thank you very much for your cooperation.
Sincerely,
Bela
