Is it true that the 1 penny flow card sold in Pinduoduo?

Because I have been cheated twice, I will answer you. I bought a penny telecom flow card with the same package twice in Pinduoduo, but I didn't deliver it to me only a few days after placing the order, and then my mobile phone number will receive a text message saying that the number card has been delivered on the way, but if you look at the mobile phone number on the text message carefully, you will find that the number is not the operator I chose in Pinduoduo at all. But the other two operators (China Mobile/China Unicom) besides the selected operator. As soon as I received the message, I sent the screenshot of the message to the customer service of the seller in Pinduoduo who sold my network card. He even pretended not to know what happened to me. When I asked him, he said that if the regional audit failed, he could not deliver the goods, so he had to apply for changing the packaging or refund. Then I said, well, since all the money has been spent, why not just change the set meal for me? The seller replied that I couldn't. I asked him why, and he said he could only retake the exam with a refund. I replied that if I did as you said, it would be useless for me to call 10 thousand times again, and I had a mobile phone card (PS) for no reason. For no reason. Then the customer service began to prevaricate for a long time and began to shirk responsibility. Think about it.
