Hifi Corp business practice, business ethic and customer service that is dishonest and *********.

on the 22 September 2023, I bought a 55'' Skyworth Smart TV. After 17 months the smart TV had issue with the volume which was uncontrollable. I reported the issue at Hifi Corp Southgate and I was informed it will that 21 days to repair as it was under warranty. I was informed that the repairs are done by an external company who will come to my house to check first whether there TV needs fixing. There repair people never came. This was round about the third second week of March 2025. Third week of March 2025, the process of requesting pictures and serial number began, which I provided. The TV was only collected on the 23 April 2025, no one came to check why the TV volume was uncontrollable to determine what needs to be repaired, just came and picked up the TV on the 23 April 2025. I called to check that the TV was received by Hifi Corp because no communication was sent and I received 2 calls from different people asking me when they should come and pick up the TV on the 25 April 2025, which raised concerns to me. When I ask about the progress of the TV on the 2nd of May 2025, so to determine the return date, the lady by the name of Tumi told me that the repair period had passed a credit note for another TV was being generated. The 5 May 2025 I called customer service, and a gentleman reiterated that the was a credit note that need to be generated for another TV and HifiCorp Southgate will contact me within 24 hours to finalize the process. I wrote WhatsApp message to Tumi and she told me that a gentleman by the name of Andile Dube was sent an email to authorize the credit note. On the 7 May 2025, Tumi told me that Andile Dube was sent two emails and he, had not rep**** the emails. On the 8 May 2025 when I followed up I was now told there's a note that the TV is on repairs. Why is has the credit note now changed to repairs? Hifi Corp business practice, business ethic and customer service are dishonest and *********.
