1. Patience, especially when trying to contact IB CS. 2. Stop complaining (customer side) & Accept complaint but remain the same (company's side). Because, after so many years, IB has not tried to solve problems. Complaining won't let them suddenly have the motivation to enhance the system, so complaining is useless. 3. Advertising is more important than continuously enhancing service. Because you can have more revenue by advertising "when you are passionate about investing, you cannot compromise....." to attract more new customers. Those people who always complain about IB service and close IB account is just a small part, so no need to upgrade the system. no need to enhance IB CS service. No need to solve complicated bugs. If old customers leave, the new customers will fill the gap.
