always money increase

The agent phones me to tell me that i need to pay R30 every month for warranty and services on the tacking devise after 1 year which is new to me and no information like this was offered when signing up.today is 03-03-2025 which i called the call center and only received my contact and terms today as i was told they don't have my email address .why should we carry cost of the device every year when we have 36mnts contract and other supplier carry warranty for 36mnt.had i known this i would never took tracker with car tack,there are other better deals out there,NB your call center agents are very rude when you talk about cancellation.
