Confusing Service

Car track is giving me run around yet I'm bringing business into the company. The only person who provided me with exceptional service was Jerome I think the guy from call centre who made my application but it seems he's the only friendly and professional person. Today when I called to ask what time does the technicians are coming to install I got through to a very rude lady by the name of Zodwa Chirwa, her tone is intimidating. She wasn't willing to help but instead she transferred me to their technical department and got through to another I tried explaining my issues to but wanted me to do what he was saying instead of hearing me out. All I want is for them to install the tracker at my parents house because there's a car pot, however the car will reside at my house which doesn't have a car pot however have wall and ADT security alarm
