Bad Service

I bought a new Tata Bold 2017 model at Tata Oostenberg in 2017. The first 6 months the car drove nice until after the first service the car started using more fuel. As my husband told them they denied it and said it's not possible. So we leave it there. A few weeks ago we wanted to trade-in the car because it's starting to cost us money and the gearbox packed up and cost us now R6000.00. I told the salesperson i want to trade the car in because the monthly installment is to much at this stage for us. According to him four financial institutions declined us. Even my own financial institution. While he was busy doing that i informed him about the gearbox he just told me it's not his problem i must phone the workshop. I would never refer this car dealership to anybody. We had to spend so much money on ubers and it's money we lose, because of *********** people that does not want to go the extra mile for you. After they sell the car to you they just don't care about you.
