We are requiring for [asked for/requested] your delivery schedule nearly 3 weeks ago, but we still not answer until now [have still had no answer/are still waiting for it]. Did your supplier already reply you how the cost of display yet Has your supplier replied to you about the cost of display? Please provide us with your schedule today. Otherwise, we are afraid you [omit - unnecessary] cannot keep the schedule for April 15 as we expected [planned/intended].

You will confuse your client by putting the sentence about the cost of display between sentences about the problem with the schedule.

Move that sentence to the end of the message.
