"Tracker"company has a poor service very poor

These people are Hypocrites ...I joined this company 2021 May and 2023 Feb I sold my vehicle and I informed them ...they told me I will continue paying until 2024 May although I am no longer using their services or I must pay R1200 for cancelation....I'm the one who went there and made an appointment for tracker installation I was never informed about the 3yrs contract and I was nvr informed about cancelation fee of R1200 when I joined......even their staff members are so rude on the phone when you speak with them .....I will make sure I make people aware about their poor service n I will make sure its seculating world wide.....they only Called 2 times when my vehicle was leaving the province and sometimes they say my vehicle is in a danger zone but it's off parked at home oh noo
