UNFAIR TREATMENT FROM SERVICE PROVIDE

Good day I'm a pensioner and ex employee of Old Mutual Insurer, my problem with New World and Old Mutual is that I had a problem with my TV which they replaced after being damaged by lighting. Old Mutual appointed New World to replace which they did in 2019 March 04, this year in February the TV just went dead, I phoned Oldmutual they told me to take it directly to New World at Menlyn Park Pretoria, Lock down interrupt after after stage 4 I asked my son to take it in, they told my son to contact insurance first my son told them that insurance was consulted and they refer us to you the deny to take and look what is the problem the TV is still under warranty which my son took it with, I call Oldmutual and relate my story the gentleman by the name of Mark Sweet called LG and also provide me with LG whatsapp number, LG wanted to know the model of the TV after I did so the told me they can't help as it is a small TV, went back to Mark Sweet, who now tell me that he doesn't no what to do cause New World don't want to communicate with him. This TV is 2 years warranty for God sake, yes maybe it's small but it's mine and it was insured and it is under warranty. They are giving me this run around so that the warranty time out and have reasons for not solving my small problem. PLEASE HELP ME
