Im not happy with their service at all

I first bought a tv with speakers (cash) in October 2024, December i then when to buy a fridge and washing machine (on credit). The delivery for the match and fridge took forever i literally had to call them everyday and i got different feedback everyday but thanks to Pretty it was finally sorted. When the matchin arrived it had a problem so they booked me a service call which arrived within 2 weeks because the head office was also involved. In Jan the tv I bought just stopped working and i went to report it and a service call was logged for it as well. To my surprise i Cindy called to to follow up and i told her the matter was not yet attended to, later i went to the store and she called the person who's responsible for the call (Andile) and she/he apparently didn't know why my tv wasnt attended to. The following day another person calls me following up again, then I advised that it hasn't been fixed, the lady tells me that it shows that the job has been done on their side. So they only take things that are on credit crc and not what was bought cash? Im really not happy and this tv is still under warranty
