I asked to be tranfered to a manager and he responded that the manager is was out. He then advised me to go to the near bank tomorrow, but him he said he will his own discretion and block my account.I then told him I'm not happy ,because I'm playing in a tournament and i wont be able to go into thw bank ,from there he insisted that he will block my account.I am so insulted and disgusted.
