SAMSUNG TV Damage goods

I spoke to the sales manager by the name of Krishen who had told me that he is sending my TV in for repairs . I received a text message telling my TV was back in the store .When i arrived at the store and Krieshan said that i bump the TV and broke it ( which is not true ). I was then reffered to the store manager by the name of Garth who also said he cannot help me and i should leave ,i refused to leave because i am an unsatisfied customer .Garth then approach the store security by the name of Francois who wanted to use force, i told the guard i will not leave until i receive satisfaction , the guard then returned with tear gas and threathen to use it on me although i had my 2 year old in my hand . i feared for my son and i left . This is not the way i should be treated my TV was under warranty and it had thin lines and then got worse. Game is a reputable store which i spend thousands on a monthly bases and funish my entire home , but customer service is extremely poor and unprofessional to pass the buck.
