Hi i had the same problem on poloniex, i tried to sens etc with metamask but it sent ETH instead, i am really desperate to liste accès to such a huge part pf my fund reserve >
"ETC to ETH"'s case is similar to that of the user above so you should get the same response.
I think you made a mistake in explaining where the restoration of ERC20 tokens is a completely different "harder than hard fork recovery."
These mistakes are personal and the platform needs to be investigated, as well as reliable people in order to return the coins so they will not do it unless there is sufficient motivation.
This is the main problem because not all exchangers do really offer out such recovery unless if the amount is just big to neglect on
yet they do ask out some fee for such service and that sufficient motivation is the hardest part to seek on thats why we should really be keen
on sending out coins on a certain designated address.
Didn't you use the escrow protection while sending the funds? Anyways, don't do that if you are not 100% secure sending and receiving fund from other users. Instead you can use some crypto exchange websites which I usually follow exchange.all-stocks.net It give me 100% satisfaction and calmness.
Stop shilling out this shitty exchange and it has nothing to do with the topic.
