TV not fixed properly

Found Pelican Television Repairs online they came to fix the backlight now the TV has a line that is not going off. It was showing from the day they fixed it and said in a week it will be off. After a week I made contact and they dodged my calls only responded to texts and promised to come fix it. Then nothing. https://pelicantelevisionrepairs.co.za/ they offer a 24/7 service +***8 contact number on website. Disappointed much
