DAY LIGHT *******/ POOR CUSTOMER CARE

They installed a tracker which they didn't do right. it shows a different location than where my car I parked. I have called them and they realized they didn't do it right and they will come to fix it. they have already started deducting money and its been two weeks without resolving this. I am scared to move with the car incase something happens and how then do they track I when its showing a wrong location. I have calls them numerous times and they tell me they are very busy and cant assist but my query was logged I must be patient. when they wanted money they were quick to deduct me. I just feel this is day light *******, I pay for something not working.
