DISGUSTING BEHAVIOUR CINDY JENKS PICK N PAY!!!

My mom bought a microwave oven at Pick n Pay Lemon Tree October last year. 6 months later it is rusted. In my opinion you it's a bad buy as you have a year warranty on most new electrical appliances and I am not happy that it's half way through it's warranty and it's already rusted. My mom followed the proper route and contacted customer care. They gave her all the information she needed and told her to go back to the store for an exchange!/refund/voucher. When she got there she went to the refund/exchange counter and the lady assisted her with reprinting her receipt as she always swipes her smart shopper card. After calling the manager Cindy Jenks the manager absolutely refused any kind of assistance and told my mother that if it were two weeks after her purchase she could assist her but it's 6 months later. The manager while approaching my mom was on a private phone call and my mom said she was speaking with absolutely no respect to her own mother on the phone as she repeatedly kept saying "Yes mom! Yes mom! Yes mom! In a very rude manner and seemed upset. I didn't know it was normal practice to be having a personal conversation whilst assisting a customer. This is very unprofessional to say the least. And then without listening to much my mom had to say totally refused any assistance in this regard. My mom told her it's not safe and a health hazard but she didn't care in the least. My family has spent hundreds of thousands of Rands at Pick n Pay, because we support Pick n Pay and have never had any problems with any food or appliances we have bought. But I must say after today we seriously doubt that we will be supporting Pick n Pay any further. Our request number is 21656. Smart Shopper ***. Transaction number 582391. Customer care person who told my mom to provide this information when she goes to the store is Zebonieta Thops. My mom told them the microwave paint is peeling and the case is coming lose as well as rusting. Which is a safety hazard. The manager Cindy Jenks said my mom it figures that customer care is sending her back to the store?? It figures?? What the heck is that supposed to mean, this coming from a Store Manager? This is absolutely disgusting behaviour from a Store Manager. We live in Boksburg, my mother travelled 22km to Alberton and 22km back home, for nothing. She is 70 years old, has heart and lung problems it was not easy for her and to be treated the way she was is totally unacceptable. I will not leave it here. I trust that something will be done to correct this.
