Have you done that since the end of November. I have had no problem with transfers for 3 years. Now things are stopped.I posted this before. I wire money all the time from my Ameritrade brokerage account to BSC.
If you did it successfully in December I would be surprised but glad
Let us know which ATM will dispense that amount. Maybe you have to make many withdrawals to get what you want. All banks have limits on amounts dispensed at one pull.Not sure what your total amount needed is, but, I assumed you can take out $1000 a day with Charles Schwab debt card, no fee, fair exchange rate. Of course if you need a LOT of money it's a big pain, but I hope to try it this month, for the first time, to take out a few $1000 withdrawals.
