it is my understanding that Armory and Electrum use different mnemonics. so you can't create the same wallets with the same mnemonic

I need urgent help with BTC withdrawals from Bitfinex.  I've had 2 issues in the past couple of days and I have sent a couple of emails without a response yet:

1- I tried to make a btc withdrawal on 10/18 but the system never sent me the confirmation email.  I emailed support on the 18th but received no response. had to cancel withdrawal request
2- on 20 Oct 00:40 I made another withdrawal request, this time I got the confirmation email. I confirmed it, and now the system shows the withdrawal as completed.  However, it is not showing any TX id and my address is not showing any transactions at all.  This is 9 hours ago.  I've sent an email to support, but still no response.

What's going on with Bitfinex?  I've never had issues like this before.

Thanks
