I am beyond frustrated with Cartrack’s service

I am beyond frustrated with Cartrack’s service. They installed a faulty tracking device in my vehicle, completely failing to provide the primary service promised in our agreement—to track my car. Despite breaching the contract on their end, they take zero accountability and provide absolutely no customer assistance to resolve the technical issue. Instead of fixing their device, they harass me daily with aggressive phone calls demanding payment and threatening to blacklist me. It is completely unreasonable to demand monthly payment and make legal threats when you fail to render the actual service contracted for. Extremely disappointing customer service and predatory billing practices. Save yourself the headache and go elsewhere.
