I have the same problem.

The payment was executed over a day ago and there have been several blocks found by 50btc since then and still the transaction can't be found by blockchain.info or any other block explorer I've tried.

Here is my transaction:

7fd473d4dd59435b3c75bbda3b800a0465ad419fe46b9a18c5469966ac1647a0


I tried going to their support but it's said support is unavailable for a day now.

Might be time to switch pools.
