Car track damage

I recently got a car and due to high crime I needed a tracking device on the car so I chose Cartrack because of what they were offering and how affordable it was only to find out it was going to be a costly exercise because during installation of the device my windscreen was cracked by the technician. I reported the matter on the their customer service line and was told a senior technician will be dispatched to investigate the incident, the technician indeed did come but what surprised me is he came with the person who was installing which is odd because I can’t complain about someone worksmanship and when I complain you bring that person to deny/defend themselves without investigating. He checked what he was checking and said will get back to me after two days till date 21/05/2024 no one from car track has contacted me for feedback for an incident that happened on around 18/04/2024 unless it’s a call of sales agent or collection
