Poor service from HI-Fi Corporation

Absolutely terrible customer service from HiFi Corp! I purchased a tablet from the Amanzimtoti branch on 6 August 2021. The tablet stopped working early May 2022. I took it to the store and was advised by Thoriso at customer service that they do not have stock of the tablet but they would call me the following week when the new stock arrives. He even referred to his manager (Perline) who said this was in order. I did not hear from them the following week so I called in and spoke to Thoriso. He advised that they do not have stock of that specific tablet but I can upgrade to another tablet and pay in the difference. I accepted this offer. I went into the store the following week only to be told by Thoriso that the problem with the tablet was not covered under the warranty. This was not mentioned previously. I asked to speak to the manager (Perline) but she was on leave. I then asked to speak to the branch manager but he was in a meeting. I have also logged a complaint on their website. I was told by Glendle Bock that the item does not qualify for an extended warranty. I explained to him that it is still within the 12 month warranty. This was the last communication I received from them (on the 21st of June). I am absolutely disgusted by their lack of customer service. Firstly, I got the run-around from their branch and now customer service department is ignoring me!
