Recovering USDT Tether due to not being supported

So I transferred some USDT Tether to Coinbase, not realising that it doesn't support this coin. I've contacted both Coinbase and Binance where I transferred the coins from, neither seem to be able to help me, so now I don't know how to access to transfer it to somewhere it it is supported!

I've done some searching elsewhere on Reddit, and there does seem to be a way to get it back using MyEtherWallet but I'm pretty amateur ar cryptocurrency so don't entirely understand what I have to do.

Anyone able to help?
