I received the package today.
Again, there are some missing items in it.
I found only one item of A(should be five) and two items of B(should be six.)
Please send me 4 more As and 4 more Bs ASAP.
This type of mistake happened 2 months ago.
Explain to me how this keeps happening.
I think you're getting more careless doing your business lately.
Please deal with this problem immediately and send the missing items.
Thanks, (your name)
