Cartrack device not ****ioning

I have a tracking device installed on my car with cartrack which it has just came to my attention that is not functioning as it should since from june 2018. I have realized that there is a problem with it when i was trying to track my car on my phone app and it was not responding, and i have sent cartrack an email were they rep**** asking for my car registration an id no. Which i gave it to them and ever since then they never gave me any feedback about my enquiry an i had to phone them were one of their consultant confirmed that the device is not working and told me that they have sent me smses for me to call them to arrange for it to be fixed and said according to their processes 3 smses gets sent to the client every week. And i then requested that he sent an email proving that they have sent those smses as i have no knowledge of receiving them and such email was never sent. And i had to call again were i was told no smses was sent.

I am really disappointed with the service i am receiving as i am not getting the value for my money. And i have been paying for a device that is not functioning since from june 18, at first when the device was installed alarm lights were not working and i had to called them to come fix them now this.
