Terrible Customer Care I still need answers.

Such shocking customer care from Cartrack. Sello refused to send me the terms and conditions of the "mandate" that the bank has with Cartrack. He told me I must phone the bank and get the terms and conditions. Initially I sent the forms to change bank details to Mbali. Suddenly I received a prompt on my phone for R800. The monthly debit order is only R119 per month. Mbali would not reply to me emails asking for an explanation. She never informed me of this charge/mandate at any stage. Terrible communication! Surely legally if I get an sms that requires me to respond I have a right to query the terms and conditions.
