Poor customer service Telkom parow

Telkom parow center worst customer service ever!!!! firstly I have explained that they gave me a faulty device in May 2020 then they got it replaced however that device just stop working in October 2021 bills are up to date done all my trouble shooting step require by the advisors from call centers whom I'm still waiting a manager callback but yet no delivers anything....I then decide to take my device back to the store in sometime November spoke to on of the agent who said they will speak to regional manager to raise my concern of device not working they called me back and told me they can't assist I then went back to the store to the store 25.11.2021 agent Hilton phillander was not interested and very unhelpful with regards to my query explain that I didn't do anything wrong and there was a outage in the area which result in every telkom client internet to be off the next day everyone's was working beside mine he was interested in my story and kept stating my device is out of warranty theres nothing they can do I then request to speak to manager Kristen then asked me what my query about with attitude I then explained why should I repeated myself have the agent not explained anything to you, I then gave brief explanation of the device that is faulty she then request book in for repair at no cost I then Gave the device only to get feedback of two months that they will not repair it they advised they attempted to call me but I don't have any records no voice-mail was left or anything ... I feel that service I got from parow center is poor customer service and don't feel like a valued customer yet I'm sitting with a lte router I can't do anything with and I have to pay R919 for something I can't no longer use which is unfair
