LEGO 77241 Missing Piece in Step 30


I purchased LEGO set 77241 from your official store today, and when I started assembling it, I noticed that a piece was missing. In Section 1, Step 30 of the assembly instructions, there should be two pieces with six studs, a rounded and flat top, but only one of these pieces was included in the box.
Since your store is far from my home and I also do not have the time to make another trip to the store, I am unable to return in person. I request that the missing piece be sent to me as soon as possible by mail at no additional cost.
My invoice number for this purchase is 0048. Please investigate this issue and arrange for the missing piece to be sent to me as soon as possible.
