Hi guys,

I've tried to exchange on blockchain.info BTC to ETH.

However the trade failed due the following reason:
"Your pending transaction expired before we received your deposit. However - it looks like we dont have a valid return address for you. Please contact our support and reference the following id to receive your deposited coins back: xxxxxxxxxxx"

Well, i've contacted their support and the answer wasn't helpful: ""If it eventually is rejected, then the funds would remain at the bitcoin address they were sent from. The only thing you can do at this point is to wait and see if the transaction is accepted into a block. Like all wallet providers, Blockchain.info has absolutely no control over this, and cannot expedite transactions. This is always dependent upon the bitcoin network of miners, which we are not a part of."

Can you help me on this? What can i do to solve this issue?

Thanks in advance
