Poor service and no feedback

Last year I approached Clientele with a situation I had. This situation started in 2016. I spoke to a gentleman by the name of Stephen Tshabalala. He advised me to go to the Bank Ombudsman and only if I do not get help there I must come back to him. The Bank Ombudsman could not help me, so I went back to Clientele. I was informed that Stephen is not in, but that a team member will assist me. After some time, with no feedback or any communication from anyone at Clientele I phoned Stephen. I was told that he is on another call and will call me back when he is free. A week went by with no call back. I again went to Clientele and asked to speak to someone higher up the chain of command. A Mr Wisdom Chauke came to see me. I had to tell him the whole story again. He promised to keep me informed of the progress with my case. I received one email and then silence. I have sent a number of emails to Mr Chauke and also tried to phone, just to hear he is on another call and will call me back, but just like Mr Tshabalala no response. I am really disgusted with the poor service I am now receiving from Clientele. In 2016 a young lady assisted me, she contacted me at least every two weeks and also send me copies of letters she send out on my behalf with regards to my case, unfortunately she is no longer working there. Maybe she was to efficient for Clientele. My Reference number P **********
