What should I do if I receive a SF reminder message?

SF is getting worse. I didn't receive what Taobao bought, but SF showed that I signed for it. SF didn't call but lied to avoid responsibility, but when I went to verify it, there was no more information. I called, but I didn't answer. So is the seller. I ask for proof, I don't answer messages, I don't answer phones. Is this collusion? Hehe, SF Express, the fastest and most responsible express delivery, is actually the worst. Of course, I can't blame the boss of SF. After all, it has a gorgeous appearance and a decadent interior. I almost went to the police when I went to the mobile business hall to make a list of call records. Because I was angry, I later thought that maybe people really needed the money, so I took it as a relief. I will never trust SF, and I will never trust Taobao again. What's even funnier is that because of this, SF wants to send a piece, and I don't tell the customer how it is. Obviously, the customer didn't want it, but SF wrote it directly without the consent of the recipient. It's hateful, damn it, even if I am a relief, I can't do this every time.
