Don't EVER by a TV from Vodacom

I have just had the absolute worst experience with Vodacom in all my years I have been with Vodacom an experience that is enough to want to cancel it all and move elsewhere.

I bought a TV on contract with Vodacom in March 2021 and and STILL paying a monthly installment for said TV, the TV now needs repairs and vodacom can't seem to provide me with any proof of purchase as my email address is not updated... and the one on record is one that I had changed 3 years ago.... Now i am trying to explain to customer care consultant Xolelwa that I had my email changed more than 3 years ago, it shows updated on my mobile app it shows updated when i log into the vodacom website she is insistent that it is not updated on her end.... She also explains to me that she can't update it on her system as I had made an arrangement to pay my current installment slightly later which was agreed and accepted..

WHAT BS is this vodacom? i am paying for a device that you have absolutely NO WAY of prividing proof of purchase for based on above and you also gave me a device that lasted a total of 24 months only yet i need to pay 36 installments.

I NEED ANSWERS this is absolutely disgusting.
