Expensive Poor Quality Products

I have a JVC TV contract with Best Home. They debit R505 for the TV I bought in Feb but the problems I have been experiencing with this TV are too much and now I can't cancel the debit because it's a debit check. A month after I received the TV it just stopped playing I went to report it at the store and it took them a whole month and 2 weeks to come collect it because they "had no cars" and I was not allowed to bring it myself. This month the "new" TV they gave me is doing the very same thing. This store is just a **** and JVC is no better but obviously their products are off very bad quality. That time Best Home is so expensive.
