Gem furniture polokwane violate consumer rights

I bought a tv at Gem furnitures polokwane on the 22 January 2024 for R14 000 on account . I paid a deposit of R1500..Tv was delivered following day when i was at work ,and it wasn't tested . I got myself a technician to come and unseal it from the box following day and the tv was not working ..I called the store and reported the matter, they advised i bring it back of which i did on my own cost . The store manager is rude, refusing to refund me or replace the tv .Now i have to pay R14000 for the tv i do not have.
