Tracker reinstallation

I’m at a loss for words at this point the service I’ve received from car track is pathetic. I still don’t have a unit installed instead I’m getting one excuse after another. I told them I have a time frame considering I need the unit done before tomorrow and I’ve been calling since the Monday/Tuesday . No one bothered to tell me that they had problems with getting ahold of the smd only today when I call they tell me this also I’ve been transferred to their customer service which I still got cut off on many occasions with no one bothering to call me back . They debited money from my account and now because I called them they’re telling me of the additional cost that I know of but could have prepared myself for had they contacted me and kept me in time with whatever is happening interms of the unit . I’m seriously not happy with the service I got and not to mention the data and airtime I’ve spent since Monday trying to get ahold of them and till today I still don’t have a unit . I also want the recordings and the contract as I was not aware of all these costs that I now have to pay . I also want proof that the car that I previously had was sold since they want to debit more money from me without giving me solid proof of the car not being available to have the unit deinstalled .To add to that my tracking app has never been activated even on the 1st vehicle I had the tracker installed in ,I ended up leaving it coz of the inconsistent service and hiccups. I need to get the so called contract so that I can take this up with the relevant authorities with regards to this day light *******.
