Delivery Man asking for Additional payment - Consumer Complaint for J&T Express Philippines

I had a delivery amounting to 1700. The money I paid was already segregated the night before. I counted the money in front of him as he gave me my package. After a few minutes he calls me back saying I just gave him 1600 when I clearly paid 1700. He caused a scene in our place saying that even if I die today you just gave me 1600. I told him I clearly counted it in front of you. I gave you 1700 and then you gave me the package now you are telling me it's only 1600. Your delivery man's name is Alex Cerace. This is an unscrupulous way of dealing with your customers. Kindly address this asap if not addressed I'll be posting this on my social media pages.
