In September 2022 I installed tracker device on my car n I took the CARE package n I was told I’ll be paying around R200. I notice that they were debited more than that. I didn’t have time to call them until on 17/02/2023 when I received a notification that I will be debited extra R260 that’s when I lost my mind and called their contact centre my call was answered by consultant called Puleng Tlhale from product support who told me the reason I’ve been charge extra is activated notifications on the tracker app. She told me that is for receiving sms from tracker regarding movements of my car and I told her I never received any sms what I normally receive it’s a phone call if my car is passing on high risk area or to call me if there’s movements to check if everything it’s order to find if I am the one driving the car. She then went to the system to check the sms’s are been send, she come back asking if I have ported to another network I told her I did that 7 years ago n she said that could be the reason but she will refer to the department where they will check if the sms are send or not n also told me a request will also be send to finance department regarding extra amount that I’ve charge to process a refund. She told me I’ll receive feedback within 72 working hours n I asked her which will on what day n she said Tuesday. It’s Friday I haven’t received emails, call or sms. She did guide me to deactivate that notifications on the app. Meaning I’ll be debited R200. On 20/02/2023 I had shock of my life when the debited R468.04. I want my refund as I don’t want to reverse the debit order as it’s going to affect my credit score n what they are doing it’s such an inconvenience because I didn’t budget for that amount
