has any one else here had issues with commsec. i am having so much difficulty with them. they've suspended my account for a supposed settlement default, which is incorrect, they didn't even ring me to tell me about it or give me a chance to settle anything. now i have an open trade that is going against me and i haven't been able to access my account to sell out. has anyone else experienced this or something similar from them. any suggestions about what i can do about it. thanks
