WORST SERVICE EVER

Horrible experience from this company. I had my tracker installed with them when i purchased my vehicle and the vehicle installment includes the tracking device installment. This people now decided to add some other service and they debit my account monthly for something i never signed up for saying when i buy tyres i will receive a discount, told them to cancel, called them, emailed them NOTHING!!! Now my account is in arrears for something i never signed up for and I'm being told, if anything happens to my vehicle, they wont track it and i'm being handed over to the credit bureau because my account is in arrears FOR SOMETHING I NEVER SIGNED UP FOR! secondly, i've downloaded their vehicle tracking app, i need to call the stupid customer service department to get my username and password. i call every single day, hold for 30 minutes and i still cant get hold of customers service. i have left thousand messages with the "receptionist" who promised to email me the details but till today, i'm still waiting. if they fail to even assist with a simple request of login details, how will they ever recover a ****** vehicle.
