Stuff with bad attitude

Horrible experience I'm stuck with a contract that is running for 36 months to cancel I need to pay thousands of rands I met with an accident and I did not have a vehicle from April till now so I called to have the 2 divices fitted in the new vehicle but they only fitted in the main device not the back up but I'm paying for both a lady by the name of Nthobisi Mbatha was very rude and tried to shut me up when I ttried to explain my story she said she can not explain what went wrong and she did not even apologize for the inconveniences caused she said she is not responsible and she can not answer any of my questions staff are very unhelpful Mercy another one of the staff from netstar refuse to give me her surname was also very rude was busy asking a question and she putt me on hold I'm now treated by an GL Attorneys to pay up or get black listed
