I made a withdrawal of 0.28633263 Bitcoins on July 10, 2017, from my Poloniex BTC address: 12iQhRSjBRaUngcDEeZE6KkuV7QQraDD8v and with a tx id: 9f063d1515539883438b7f995e47a9c9df91258b657a88032b6fa1bbfccfbc48 to the address 1B9VAjA9ABzV2xUsEkQS5y6ynvJCLUJGX . This address is a payment management service , his name is Chip-Chap, his website is
https://chip-chap.com/.
I had a problem using that external service and asked for a refund of the money. They sent the return, but instead of reaching my Poloniex BTC account, it was deposited in the BTC account of Poloniex 17A16QmavnUfCW11DAApiJxp7ARnxN5pGX
The transaction returned from Chip-Chap can be consulted in photo 2. I copy the details in text.
