Dear Christophe,
Thank you very much for your arrangement. I’m very sorry to tell you that our engineer are fully booked during that time and all the way till end of this month. Without any confirmed PO, it’s quite hard for us to arrange the manpower. I do hope that you’re understand. I’ve notice that my team have send you the quotation for before request trip. How about we prearrange this request around mid-Jan 2017 and in the meantime your side would have time to sort the previous and recent PO concern. In the meantime, if your side need any phone support, please feel free to contact our team and we will fully support you via phone. Thank you very much for your support.
Best Regards,
Sam,
