Tv complaint

I bought a tv from Best Home and Electric in Wynberg last year and now the tv has a line in it and i’ve laid a complaint 7 month ago and i went a few times to the store , all they tell me is that they coming to fetch the tv but they never came to fetch the tv , i sent a email to the head office still they didn’t come back to me. If i go instore then the agents there or never mind just every time telling me they’ll fetch the tv nothing happened. i’m waiting now for 7 months ! it’s unacceptable! the service in that store is bad ! The agent that i dealed with , “ASHLEY PETERSON” I phoned him also few times concerning this complaint and he hasn’t done anything to it , same story over and over , his waiting for a Job number from head offices and for them to get back it him , does it take 7 months for head office to get back to him. Im honestly disappointed with this shop , every month they get their money but this is the kind of service they are giving me.
