Shocking after sales service

I purchased a 40 inch TV on the 30th Sept 2018 from PnP Oribi Plaza. . Line right through the screen. PnP told me to phone hisense myself as they dont deal with the TV after 12 months. So logged a call sent emails to Hisense. Technician phones me on Tuesday. Told him I am available on Friday as this is what told the call center. Today I have phoned twice to confirm for tomorrow and the technicians cannot give me answer as they dont have drivers in the branch. What the hell Hisense.
