Thank you for your feedback. I’d like to clarify the points you raised: 1.While you know your event was on the 20th, you initially stated four times that delivery before the end of the month would be acceptable. 2.I informed you in advance that the shipping cost was an estimate and would be recalculated after production, as stated in the contract you reviewed. 3.Your initial choice of air freight met the original timeline and cost. When you later requested delivery by the 20th with only six days left, express shipping became necessary, increasing the cost. 4.UPS delivered on the 21st due to weather delays in the U.S., which were beyond our control. 5.Our company policy requires shipping payment before dispatch. While you mentioned payment was made, I requested proof multiple times but did not receive it in time. 6.I have resent the contract as requested and clarified that UPS invoices are issued monthly, so I cannot provide one immediately. Thanks for your support and understanding.
