You said, that everything is alright, but there are still delayed payments. OKPay is still not accepting bitcoins(afaik, they stopped accepting bitcoins, when you started delaying wire payments). I have one delayed withdrawal to OKPay(it's 4 days old already), support gives some silly explainations. What does that mean: "We have retried your withdrawal and will inform you once it is processed." ? What's there to try? You can only do that transfer, or not. There is nothing to try.
at a guess they sent the TX and are waiting to see if it bounces back.
International bank wires are slow.
