No accountability taken at all

I’m so angry with the service my Mom received at the store in kenilworth center, and what frustrates me the most is that it takes a lot for my mom to be upset, we needed a mop, and the African lady gave us great advise and we told her we will return back since we wanted to do some shopping first, and upon our arrival we were assisted by Zahinra, firstly she is soooo *********** and does want to take accountability at all for her wrong doing. My Mom made a purchase and she got the confirmation in her phone, she then insisted that it didn’t and said the machine doesn’t work properly, even though my mom was a bit sceptical she did the transaction again as she had put her trust in her, and the second transaction sent her another confirmation, she then again said my mom she reattempt for the third time the nerve, even after my mom kept showing her the confirmation, as my Mom was going to do it the third time, the African lady intervened , Thank God for her, and advised her colleague otherwise, that’s when the head office was called. What frustrated me mom, this Zahinra girl kept telling my mom it’s not her fault, which clearly it is, and the fact that she doesn’t want to take responsibility annoys us the most. I’m all of that, after my mom was refunded, she infact wanted to cancel the inter sale but the other consultant advised her otherwise as she knew how much she was excited about the product. When we got home we discovered that my mom had left her phone on the store, that’s when she flipped, cause if it was not for this *********** girl her phone would have been in her bag, we now had to loose out on petrol to drive there whereas that was never the plan, basically she has cost us alot. And when I got into the store, she still insist it was not her fault, what madness is this.
