UPI Fraud Related Query

I saw a channel on telegram where they were advertising that they could sell phone at low price. I send the guy 9000 but then the guy blocked me and the phone also did not arrive. On the next day I reported the incident to cyber crime portal with all details but after 9 hrs only I received a message that my case was rejected. After 8 days of that I again received a message from cyber crime saying a bank account was on hold for the amount 9000. The next day the scammer contacted me and sent me back the 9000 but through a different UPI number. I tried to withdraw my complaint from cyber crime but they told me it was not possible and the complaint will not be withdrawn until there investigation is complete. Am I in legal trouble here as the scammer send the money back to my bank account?
