Discovery cannot resolve customers queries...

I paid for a stand alone DQ track to be installed on a car that I purchased in December. Discovery only installed the device at the end of January and up to date have not loaded the device on the DQ Mapper. I called their call center on numerous occasions and keep being told that I must check again after 48 hours. Nothing seems to be done. If thats the case Descovery can have their device removed and refund me for the installation and the monthly premium I have paid for the device. Their service sucks......
