Statements are received after Clearing house. That means all your buys vs sells are matched up. It's not AMP employees making billing mistakes. However if you think there is a discrepancy you should call them. I was on their chat the other day and it was fine...AMP's business flies high and I guess their employees are overloaded. They now often don't reply to emails and make billing mistakes. Watch your daily/monthly statement carefully. Chat service is also not very helpful these days. They just refer other email addressees to contact. Good to see their business is doing very well anyway.....
