Extreme Bad Customer Service and Lack of Taking Responsibility

I app**** for a tracking unit from Netstar and the sales person failed to be transparent to provide me all the pro's and cons of the device, now I'm sitting with a device that is not acceptable by the insurance company I'm with and no one at Netstar is assisting me but rather they are billing me for a useless device and refuse to nullify the contract (even though the contract is 15 days) There are other companies that provide a tracking device for R99 that is accepted by insurance companies. Netstar refuses to take responsibility for their lack of taking the onus to better educate consumers on their devices on what they cover and if they are accepted by insurances. I've been battling to get this issue resolved for almost two weeks but no one is coming with an acceptable resolution... Now my car is currently not covered for theft. Very disappointing service... Look elsewhere for a tracking device and stay away from Netstar.
