Is Tencent Music Partner Real or False?

In the group of 20 19, a person who claimed to be a co-promoter of Tencent Music Company added me and claimed that he could help promote the work, provided that he signed a copyright contract with him. After I signed the copyright with him, this song was sent to the qq music platform, but it has not been promoted and I haven't got a penny. That song has not been reviewed, collected or promoted for a year. I realized that I had been cheated. Everyone in this group can join only at the invitation of the group owner. Today, when I tried to expose other friends of the same nature in the group, I was maliciously kicked out of the group chat by the group owner. I asked her to respond positively to my questions, and she never responded positively to lies.

At that time, I didn't understand why such a large group was built, but now I understand. Because I haven't spoken in the group for more than two years, if it's for communication, then why did I kick me out as soon as I talked about being cheated?
