I also have this problem. I bought coins from an ICO called OALEND. I sold and made a withdrawl. OALEND sent the transaction using chain.so
It has been 10 days and I still have not received a single confirmation for it. I think this is because the mining fee is too low and they maybe keep sending transactions off unconfirmed ones or something so they can skimp out by paying super cheap fees??? I would be willing to pay someone to help mine this for me. I am at a total loss and don't know what to do. Here is the TXID which only works on chain.so
