Teljoy likes to change their mind when they can't answer questions

I bought a TV though teljoy a few years ago, during this year the TV started showing dark spots on the TV and i report same to Teljoy where they said that they will get an tech to come an check if the TV can be repaired or if it needs to be replaced, waiting for over a week a tech showed up that checked the TV and said they will go an look if they can get parts and let me know, no feedback was received and i had to follow up where i was told that the TV cannot be repaired and they will give me a suitable replacement, I had a Samsung Curve that i paid Teljoy over R 22K over the term of the contact that never defaulted on and they gave me a replacement of a Hisense saying it's a suitable replace, i wasn't happy and when speaking to an agent from Teljoy i asked how is it a suitable replacement and how do i pay R 22K for a TV and at the end of my contact it breaks i get a R5K TV as a replacement she told me nothing can be done and i can even take it to the NCR. Today not even 2 hours ago my house was struck by lighting and when calling Teljoy because they debit me still for Maintenace i was told that the Maintenace doesnt cover act of God lighting and when i advised the agent i was speaking to that i will take this to the NCR he changes saying they will send a tech to come and have a look at the TV - this is not in terms of the TCS Legislation that you can change your mind that suits you and i will take this to the NCR asking for the deal to be cancelled and for all the money i paid to be refunded and Teljoy can take their suitable replacement as you pay for something that doesn't materialize as per the contact
