Regarding the missing package that I have been asking you about for a while, has there been any change in the situations?
If there are no improvements in the situation at this point, I cannot wait for it anymore.
I would like to receive the guarantee for the price of the products.
If you need it, I could send you the documents to prove the price of the products.
Please attend to this matter and reply immediately.
