Have you been experiencing this before? I have been using bitstamp for a while and i haven ever had this kind of issue about my withdrawals.
I trying to withdraw money & BTC for a weeks but I never get confirmation mail. Have somebody else similar experience?
And i am usually withdrawing often, maybe once a week or so.
Why dont you try to withdraw your balance in other currency instead of BTC? Maybe this could work, i had the same issue on other exchange, and i wanted to withdraw bitcoin and the confirmation wasn't reaching my email.
I just waited 15 minutes, and i withdrew eth, in a few minutes i received the email and the ethereums on my wallet.
Maybe this could help you out
