Bad service from Charlene at Dotsure (Netstar department)

Hi there, I called Dotsure at the beginning of December 2024 to get a quote for a new vehicle I was considering purchasing. I then called Dotsure around the 2nd week of December 2024 to add the vehicle onto the policy, before taking delivery. I asked to have the old vehicle removed (Kia Picanto) and have the new vehicle added (Starlet Cross). The consultant who assisted me at the time didn’t mention anything about having the old tracker removed or she didn’t mention anything about me being liable for the old tracker from the Kia Picanto. I then called Dotsure in February 2025 and spoke to Charlene from the Netstar department who mentioned that I was still being billed for the tracker of the Kia Picanto, she mentioned that he will have the vehicle removed off her system and I will receive a discount of approximately R127 per month. 3 weeks passed and she didn’t contact me. I was now told that I am liable to pay for the tracker off the Kia Picanto. Shouldn’t this have been mentioned to me in December 2024 when I called to have the vehicle removed off the insurance. I am beginning to lose faith in Dotsure and their staff. Can someone call me urgently and assist.
