False advertising and do not care about customers

I have registered a claim with Absa idirect house contents ,we had a lightning strike and my TV got damaged ,they rejected the claim saying its insects that burnt the power supply and left traces of lightinig don't know how that makes sense to anyone and they are fully aware that there's was definately a lightning strike but they are being unreseanoble ..we then took the TV to another service provider who then supp**** a report with pictures indicating and proving it was a lightning strike that caused the damage but ABSA is refusing to pay and the real reason is because the TV parts they are irreplaceable and this means they will need to buy a new TV that is why they are rejecting the claim what they are saying about ****roaches doesn't make sense and its not true,This is not a good way of treating customers especially a reliable customer who has never claimed for anything ,i have covered my car ,phone and house contents for over 5years and never claimed,all they care about is to deduct premiums and not pay as they advertise,whats the point of having an insurance that will not take care of your when you are in need and yet you are paying every month without excuses.What a very bad first claim expirience
