Dear Ananth,
As my explanation over phone, the raw material quantity has been fixed two weeks ago. We cannot increase delivery even arrange over time work. For the balance demand, we already try very hard to speed up production. We will arrange more delivery in W1 Feb. Kindly understand.
One thing need your help. Despite we received new PO yesterday, the quantity is not enough for your demand. I think it is the main reason why we cannot deliver ESR to you in time. Because, we have to very careful to control our raw materials. Kindly help us to solve this problem as soon as you can. Thanks.
