Horrible terrible service 😢

So I've been a client for years of cartrack the first incident was when my tracker expired because it's been over 3 years firstly cartrack never contacted me to tell me that my tracker expired before the 3 years or even after the 3 years I had to find out by myself that it only lasts 3 years they made me Pau for something that never worked the second incident is their horrible communication on their WhatsApp platform I've been trying to change my contact details but still no luck 😢 the other incident is when they had to come and replace the tracker I always make an appointment but on the day of the appointment the technician never comes nor shows up when I call in they don't know where he is but my latest incident is the worst shame 💔 😢 😞 a technician finally came after 3 months of trying and putting them under pressure but now my app still shows dates from 2022 and shows my car has no signal but yet I have a new tracker when I ask on WhatsApp they said I should re install the app I did all of that still no luck until they said my tracker needs maintenance now I couldn't understand if it's new why does it need maintenance till today cartrack hasn't phoned me to schedule my maintenance my app is still not working but they making me pay for services not even working I'm so irritated and upset I wanted to cancel from the time my tracker expired but now it's getting out of hand because I keep on have to repeat myself about my contact details and I have to keep on being rude in order to get assistance no man it is tiring and highly irritating 😢 cartrack is disappointing now
