Extremely poor service in store, plus no telephonic feedback

Extremely poor service in store, plus no telephonic feedback, nor any resolution towards outstanding monies. My 80 year old mother is trying to get the last of her retirement money. She was in store in centurion, and got extremely pathetic help, to the point where she started to cry out of frustration, when i stepped in, we were made to feel like inconveniences where the assistant started screaming at me because i took her on about her attitude. the manager stepped in, and promised my mom it would be paid end September. It it now end October. NOTHING. Trying to call the help line is a JOKE. Not only do you have to hold for at least 15-30 minutes before someone answers, but then its always the wrong department, and get transferred to someone else. I have wasted around 80minutes of airtime waiting inline. I have to every time explain the whole story, and when i get mad at this situation, they drop the call. WHAT SORT OF OPERATION ARE YOU RUNNING THERE????????? Please can someone call my mom, and help her. Her nr is ***, and mine is ***. PS, i can only imagine that this message is also going to be ignored, and that no one will assist........ PATHETIC
