Just received a phone call from them. Starting asking me why I'm not doing anything with my account. Told the guy I'm trying to withdraw my money and want to close my account.
Also told him that I said the same to his colleagues. He apologized for the fact that his colleagues were rude / impolite. He still tried to convince me to continue with them. In the end he respected my decision.
Next to that, still no reply from the finance department. Will contact my bank tomorrow, running out of time today.
