Frustrated is an understatement

I wrote a review on Hellopeter in June 2025 and up-to-date I haven't received my refund since I was over charged for 4 years but instead I keep getting call to pay for the 2 months I reversed payment of my debit order of R459.00 , how does Cartrack have the nerve to request I pay R459.00 when they owe me R6400 for the 4 years they overcharged me after my contract was expired they were supposed to debit me R99.00 but they debited me R242.00 for 4 years. Since they wrote on hellopeter that they were going to investigate and get back to me , I'm still waiting for the email or call but instead I get harassed by the accounts department and also whatspp to say I must pay R459.00.im very frustrated by cartrack I would never recommend them to my worst enemy.
