Bad service and not taking customers needs serious

The bad servuce i received in tembisa plza railway it seems as if they dont know what they are doing, i bought tv at railway tembisa plaza and is under guarantee it happened that the tv doesnt play anymore we went to the shop 2 repirt the matter they told me that the tv will go to repairs that was june 2020, i went to the shop beginning if july 2 check how far are they they told me is still in repairs, i went back again beginning of august what they told me 2 different stories tjat dont make sense tjey said my tv was damage because of water in my house the is no lickage and tjey also chang and say eletricity berned my tv i asked them how ciz the is eletricity protector. I feel like am not taken serious at railway tembisa, they dont take my issue serious they keep on postponing everytime when i go tje 2 check on my tv, the dont do followups to let me know how far the repairs its been three months with out my tv yet am expectwd to pay full installmentcan their service department get hold if me railway furnishers tembisa doesnt have a sense of agency to its customers
