ЗАДАНИЕ № 9.
Dear Sir,
I am writing to inform you that I have still not received payment for delivery payment of 40 dining-room chairs.
I would be grateful if you could make payment within the next 10 days. If we do not receive payment, we will be obliged to take legal action. I look forward to hearing from you in the near future.
