Fed-up

I have been struggling from July 2023 to cancel a subscription on a vehicle that has been sold the year before. Call after call month after month the same promises with the same outcome. they still deduct money from my account. They ow me the premiums from July 2023 till December 2023. They only reimburse me with 2 Months credit notes in January 2024. However they deduct December and end of January again. After I canceled the debit order at the bank and reversed the payments, they send me a email stating my account is overdue. What a joke. I did speak to two lady's( Carmen Samuels and Ntuthuko Gwensa) in this time and send my cancelation application to both of them and still cartrack takes my money. Some one gets paid for not doing there job (nothing new in South Africa)
