MAKRO SPRINGFIELD SERVICE

purchased a tv unit and it gave a fault within 30days of use.. makes a screeching sound while watching and switches off after couple hours of watching.. took it to makro and they sent it to repair agents, came back saying no fault pick tv up at makro.. i told makro i will not take the same faulty tv back as clearly we are watching the tv hence we see the fault.. and since the tv was faulty under 30 days of purchase i require a new tv unit.. they refused and said not possible as the decision is on repair agents, i call repair agents and they said makro makes the decision they are just repair agents.. went back into store as their lines dont work and they said come next day and manager does not want to come out and says just tell them i will call tomorrow and give feedback, next day comes no call and we go back into store and the manager only comes out when we say we have recordings of agents call and their conversations also.. she said she will get back tomorrow again.. we are going in circles and so dissapointed.. never been treated this way GAMES SA.. first time purchase at makro, will be last... for a 30 days old tv wow terrible service.
