Device installation

My name is Khethiwe Mahlangu. I just a bought a car on the 27th of June 2022 financed by Nedbank and insured by Absa Absa told me they work together with Glasfit and they are going to call me for arrangement of device installation they do call me the very same day for device installation and I was at work I didn't answer the phone they sent me sms with the ref no ***. I called them numerous times and even send them emails no response from both of them and they deduct the money every month and the device is not yet installed.
