Harrasment, unauthorized deductions, no actual help received.
In brief, 9 times a day for 2 weeks been harrased on the phone by them trying to force payment for an upgrade I decided not to take. They still took the payment.
When the payment was taken, the phone calls stopped, but try getting a hold of them.....
Eventually when I did, they acknowledged I cancelled the upgrade and they owe me a refund. Again what a joke! I never received my refund. After a month waiting, I got upset as now not a single phone call with the slightest update.
By this time I decided to cancel the debit order with the bank(unsuccessful), however did manager to dispute the amount that was taken, this initiated an immediate recall of the deduction at a cost. (technically the bank reversed the payment, not cartrack refunding my money). 

Now I'm been harrased again via phone, for a monthly payment I'm denying them. Read further. 
In the time this all was happening before the upgrade deduction, I sold my car. Immediately after selling my car I informed them about this and wish to cancel. I was told I cannot as there is a cancelation fees that needs to be paid as the service is a 3 year long contract. Fine I get that... I was happy to move the service to the another vehicle within my family circle(I had not agreed with cartrack on this decision yet), up until the point they did an unauthorized deduction on my account after clearly communicating with them I would not be taking the upgrade. 

Each time they phone me I keep telling them the same story. What surprises me is each consultant spoken to from how many departments they have, have all logged my story into their system, if this is the case why am I still getting phone calls asking for money instead "sorry we have failed you, how can we resolve this". Again like today. I was told " we have logged your concern, a consultant from account/customer service dept will contact you shortly". Yet between cus services and accounts there is clearly no communication as consults from both keep telling me a consultant from the other department will contact me to resolve the issue. 
Now I so aggrievated that I no longer wish to use continue using their services. Their departments seem to not know what their actual purpose is except (by reading the reviews) , is only to harass people and not provide a service at all. 

I'm so glad I never had to rely on the actual service they are supposed to be providing as this continue never ending encounter with cartrack is telling me that this could be the reflection of the actual service they provide. Therefore my safety concerns just cannot rely on them. 

Before I forget. Cartrack was informed 2 months ago, numerous times of the sale of my car. The buyers of my car have already sold it to someone else. Guess what... Cartrack system still says I own the car... I mean really, and you expect me to continue paying you for the safety of wellbeing when you can't even keep up with the facts.
