Curtis Brown false representation on how there selling there warranty plano Texas

I was sold  property insurance on a television i purchased and was told by the seller that i will be cover for any damage that may happen.I was also sold a television that may have been refurbish due to (2) other television I purchased from this same location. I was rushed to be up sold a higher dollar amount from the seller. The screws that was giving to us to use on the television has cause damage to the tv. this happen 28 days after we purchased the tv. We called and we called. They waited until 33days after the purchased was made to only find out the tv was not cover  and now there are giving us the run around. We also made another purchase where there put proerty insurance on that ticket when we told them we didnt need that type of insurance due to us already having that insurance.the seller at this location need training on how they sell. the manager as well.
