To Email My Supplier

I just shoot an email to a supplier for the second time since he did not reply me the first time. We need to know how to join the different layers on the floor and our business success with this company depends on this information. I hope they will reciprocate soon with the much needed information. It is no point doing business with a company where no one reads the emails and there is no prompt reply. I hope they will look into it and send me pictures if possible. That is why I always check the company emails every morning and evening to correspond with people and to reply them in a prompt manner.
