Poloniex could return the transaction back to the Chip-Chap address and I could solve it with them because they have been interested in my problem at all times and have maintained contact. The only problem is Poloniex and its obscure business policies and its inefficient support center.
It is also my fault for sending BTC from an exchange to an external service, I have to recognize it. But there is no right that Poloniex retains my funds for more than 8 months, staying with my Bitcoin Cash and all the bitcoin forks and even all the trading opportunities I've had during these long 8 months.
I opened the ticket the same day of the problem and I did not have an answer until 6 months later
