Poor Service delivery

Since cartrack damaged my vehicle rooflining while installing an dashcam they have made no attemp to fix the damage they caused.i asked for the dsshvam to be removed after i cancelled the subscribtion due to the damage. They swithed the dashcam off immediatly. I get now phoned daily about payment for the dashcam. When i asking when the damage would be fixed they cant provide me with an answer. The service is really sad. Do not join cartrack.
