Binance, Ether sent from Bitstamp never received

Hi guys,

I have a problem with an Ether transaction. Going on order: several hours ago I made 2 withdrawals from Bitstamp and I sent some Ether to Bittrex and some Ether to Binance. Those sent to Bittrex arrived very quickly, those sent to Binance never arrived, and they're not even "pending".

I've already contacted both customer services, due to the time difference I'm still waiting Binance's reply, in the meantime Bistamp told me that on their side everything is fine, and they sent me the transaction code, which is this one: https://etherscan.io/tx/0x4dbd79327c3c101f6a061ca96c9bd5e2356401e3e9634c4ee96568fc419c229f

Does anyone know what's the problem?

And checking all my transaction from my Binance address (https://etherscan.io/address/0x51efb35496ced0ee2007259b3246eda6925d8f72]) there are other 2 things I don't get:

1. Why in order to visualize the missing transaction do I need to select "Internal transaction" and it's not together with the other ones?
2. I see there is an OUT operation for almost 11 Ether, I never made such operation, I only moved 11 BNB (10 without the fees) from my Binance account to another address, and nothing else is missing on Binance, so what's that operation?

Thanks a lot! :)
