Bad customer Service

On the 20-07-15 I entered into contract with Tracker SA asking them to assist me if my car gets ****** they will be able to assist me in tracking the car, for the first 3 months all was well up until I received an email from [Email Removed] informing me that they have not received any movement from my vehicle.I then called the number on the e-mail only to find that the number on the e-mail is forever engaged ***),then I called their call centre and asked to be put through to the sales department and the transfered me to Product support.I was assisted in January after I had to fight with them and asked to speak to the manager however in February I encountered the same problem I called the device was reseted only to work 1 day last week the 09-02-15 got another email from [Email Removed] advising me that they haven't received movement from my vehicle like the previous time I called and asked for the unit to be replaced with a working unit was told to wait for 48hours which has passed and no one has contacted me or apologized for any inconvenience. I called today and waited for more than 30 munites without any assistance.<br> Had I known that this is the kind of service.
