50 Inch Hisense TV went blank within 7 days of Purchase

My mom opened an account on the 8th Jan 2025 and on the 10th of Jan 2025 she got at text message confirming that her OK furniture's account has been approved, and same day she got a call from the store sales consultant consultant confirming that the account has been approved. On the same day of the 10th Jan 2025 my mom then went and bought the 50 Inch Hisense TV which was delivered on the same day of 10th Jan 2025. The problem started late around while she was watching Uzalo on SABC 1 around 20:40 when suddenly the TV went black and only sound was coming out on the 16th of Jan 2025 to this day. My mom then went to the store on the 17th of Jan 2025 to complain and she was told not to bring the TV to store but the store will send a Technician/Assessor to view the damage of the TV because they could confirm either the TV must be replaced or whatever. The store requested photos of the TV and till this day nothing has been happening, and we still don't have a TV to watch. Can OK/Shoprite furniture do the right thing towards its customers and sort out each and every claim that arises as asap as possible before the Law comes in knocking. Do right by your customers.
