Pinduoduo platform shopping, merchants do not deliver goods after payment, does anyone know the mystery?

I also met a single order, saying that it was a month before the year, and then caught up with the epidemic, and I didn't ask for delivery. It was not delivered until about March after the year. In this case, the merchant is suspected of applying capital turnover. In this case, you can turn to Pinduoduo official customer service. The official customer service is still relatively good and will definitely give you a satisfactory answer.
