Billed for Sms because Car Guard not working

had a 36 months contract from 2019 Dec. I then sold the car i had the tracker Feb 2021 and owner wanted the contract to be transferred to them.

Feb 2021, I had a tracker installed on my new car and asked them to duplicate the same plan. Around late Feb I called and complained that my car guard was not giving alerts when the car was switched on and off. The person said they will escallate the issue.I think this was around the time I set up the sms notification and was not aware that you get charged per sms. Today I receive an invoice and I am charged 192 for sms. My car has been at the workshop and last sms was on the 8th March 2021. I called today spoke to Lebohang and could not disable notification but she was helpful. She transferred my call to Sthembele who started by shouting saying i set my notifications. So while I was with her on the line,I was able to see where to disable the notification and was cut off because I ran out of airtime and she did not bother to call me back. Now here is the thing, the only reason I set up the sms notification, was because there was an ongoing issue car guard functionallity and I did call and complain and for the safety of the car, I needed to find an alternarive of knowing when when the car is being switched on. That functionality was not working and I had paid for it. I am not happy about paying for the sms fee,as Tracker was mainly responsible on the decision of setting up that notification.
