I would admit the cex.io is the worst broker I have ever used. I mislead with one of my friends and use it. It is very expensive, the supporting guys do not even give any shit about you. Do not use it!!!!
Anyway, I am a pretty newbie to BTC, my transaction go stuck, I cannot broadcast it myself as it is not set by me and do not have any private info, I cannot increase the transaction fee, and I do not get any reply from the support on cex.
The block contains a lot of other wallet addresses, just one of them is one. I really do not know what should I do. I lost already $300 on this issue. I post this one here in the worst case at least other do fall for this cex.io website, and also if somebody can help me to resolve it.

There's one way that you can get it confirmed yourself: child-pays-for-parent. You would need to use the unconfirmed output you received as an input in another transaction, then pay high fees to ensure a miner will confirm both transactions. From the look of that transaction, it's not worth it.
The only other thing I can suggest is to submit the transaction to this site near the top of every hour until they accept it:
