POOR SERVICE, NO FEEDBACK , PUSHING OF SALES

I recently called car track to install a tracker, the WORST DECISION I'VE EVER MADE!! they sent a technician who could not finalize the installation as something was not tested and i immediately thought to myself what a bad first impression!! he came back the next day to finalize the installation and the tracker was so visible as it was on my seat belt lever and i even asked him about it and he confirmed that it won't be a problem. hardly a week later the glue used to attach it is already loose as the seat belt is something that i use daily, hence my concern when i saw where it was??? I called them to inform them and they promised that someone will call me back, I'm still waiting for that call 1 week later, i sent an email to their customer care no response!!In the meantime they have already debited my account whilst I'm still waiting for a contract and right now I don't even know if i'm safe as that thing is already coming loose, like what type of incompetence is this!!! they just want sales and so quick to debit accounts and selling a rather false service. no feedback, no customer retention !!! Like i want to cancel cause i don'T EVEN HAVE A CONTRACT ANYWAY... DON'T USE CAR TRACK, IT'S THE WORST SERVICE EVER!!!
