I hate the fact that I have to CALL my broker to complete transactions.

They don't do currency conversions unless necessary so I have to buy on margin then call them once the trade is settled to convert my USD into EUR to cover it. If I do it within 2 days I don't get charged any interest, but trades are settled 1 business day later so it's kinda marginal.
I called them today, they said they'd do it, and it's still not done 10 hours later. I have to call again tomorrow.
