PEP Store Poor Costumer Care Service

I am very unsatisfied with the treatment I had received from PEP Store (Randburg Square); I had purchased a Mobicel Phone on 21 Dec 2021 and after a few days of having it, it stopped working. I went to the store and raised my complaint, within the 7-day replacement policy, and my complaint was completely disregarded by Mosibudi, Pulane, Thami Fina(Area Manager). I then reported the problem again, but they still didn’t listen to my complaint, instead, they wanted to book it in for service rather than replace it. I find the treatment of the store towards its costumer unacceptable, hence they show a lack of customer service and they would rather not listen to their costumers' problems, but instead try and manipulate me.
