Is this the token you are talking about?
https://coinmarketcap.com/currencies/piggycoin/#marketsOn coinmarketcap you can see all the platforms which list the token. You can try sending the tokens to another platform, if you failed the first time.
I would suggest you to first send few tokens and then sending the entire amount. You will pay the fees twice, but at least you will not lose your money!
I've tried to send to one exchange but wallet address is not support in MEW, wallet address begins with the letter P while in MEW must begin with the letter O
