unsatisfactory customer service from absa

I am beyond disgusted and absolutely fuming at Absa branch, not only are your employees completely useless, have major attitudes and completely unhelpful but whenever my fiancee and i go into a branch to get the issue resolved of money disappearing from his account(which has been happening for over a year) nothing is done about it, money is not returned, no internal investigation carried out and no feedback on top of the fact that every time there is a different excuse- last time it was the card itself that was an excuse, so ordered a new card, a few months later it happened again- again the card was being blamed which was nonsense, we then insisted on getting 4months full transaction to see what irregularities were in the statements, all places were accounted for and money was still unaccounted for and simply vanished with what appeared no reference. after being told we could expect feedback from the investigation we received nothing. and surprise surprise money has vanished again, when called to find out what was going on? the answer just come in to the bank or wait until we email you your statements- no mention of an investigation or what can be done to stop this. we are at the point now where we are looking at going to the newspapers, carte blanche and if more people can assist and tell us if this has happened to them possible legal action as money cannot just disappear as we are sick of dealing with unhelpful, under qualified people without getting an answer from anywhere!!!!!!
