Unfairly untreated by a manager and verbally abused by her. I want my money back.

I am not happy with Ackermans service. I lodged a complaint against your store and bully from B6 Tzaneen manager and today the same manager had a gut to call my mother to meet in the store, Doris (manager) harrassed my mother (in her 60s). I gave Doris a letter from court demanding refund few months back, i never received any email or call from head office. And today she harrassed my elderly mother in the store, for heaven's sake what's going ln with people you hire? Now my mother's high blood is too high she's admitted. My mother was insulted about her age and told her I will never get any cent from Ackermans. I bought that cellphone with my hard earned money, and I also have a right to demand refund. I no longer want any cellphone agreement with your store I want my money back. And since you are letting Doris get away with harassing people who's the next victim? Are you letting managers harrass and abuse people since she (Doris) said head office gave her an order to do as she please and we'll never do anything about it. Doris'words sent my elderly mother to hospital so she then block me on whatsapp. Stop abusing people's rights and pay me back. I worked really hard for that money.
