I have done trades with listed ads. Means i sell btc from my mining income with listed ads. Mostly small amounts as i withdraw from cloud mining contracts. I preferred ads with trade history of minimum 1000 trades with 100% good reviews. Also trade volume is not huge . Majority of them are active now. By the way i have stopped trading in lbc and moved to exchange. Zebpay and unocoin are available right now. I thought they are not providing services like changing btc into fiat. By the way they are working fine now and plan to leave peer to peer platforms and they are not feeling safe. Also amount is my bank is not a big amount. So i plan to call bank manager frequently and wait for an update from my bank instead of spending a lot to lawyers .
Good to know that the amount was not big and you're not worried about it. But I still wish you all the best and I hope you get your account and money back minus the transaction which went bad. Please do not stop pursuing this because all accounts are now linked with PAN and Aadhar and it is not very difficult for authorities to track them.
You say that the many of them are still active. Check the non-active ones and see if you can find out something. Read negative reviews left to all of them and see if someone else reported something about charge-back or stuff like that.
And if you do happen to find out the culprit who did this. Kindly, let us all know. So, we can avoid them.
As the saying goes 'One bad Fish spoils the whole Pond', action of one bad trader will affect so many others and even the rating of the platform.
