I was thier client after I bought a car in 2021 and the dealership suggested them for the car tracker I did not have any bad experience with them until I bought a new car in July this year and informed them that they should cancel the contract as I have inserted a tracking device from another company in this car They have been debiting money from my account eversince even after numerous WhatApps , e-mails and phone calls The last straw was today when I went to the garage for petrol with my last money only to find that they have debited again today I have been Reversing their debit orders and this has led to my credit score decreasing
