I'm just curious. If they need up to 3 days to add funds to neteller acc then on what rates are they doing it? If you are sending 1 BTC to your account then for 3 days the difference between rates can be worth hundreds of USD in usual time and up to thouands of USD during different pumps (like we had some days ago).
P.S. OP, please post here an update when the situation will be resolved.
