No service or communication

While I thought I was enjoying a bank with good monthly charges, it has been a nightmare trying to get any direct help from them , have sent several emails just to get a comfimation letter for over 2 weeks and no one has bothered to get back to me. There is no beach to go to for help . So i need to understand what is one to do in this situation? Because your lack of communication is costing me money and a huge inconvenience in my life. I might as well go back to fnb service was way better than this . The least you can do is to have more options for self service cause this is ridiculous.
