Useless and poor service

I'm currently experiencing a poor customer service from Car Trak, I called in for a downgrade and the agent explained the process and the costs included. The debit order with a payment of R350 went through on the 25th and I was also told to expect a call for a new fitting of the device sadly till today I haven't received any call. I called in on the 5th of June 2026 and I was sent from pillar to post with no one assisting me with my query. Kindly assist me with intervention as I cannot afford the new premium which has increased since 25th May 2026.
