Shocking service to Retain a client

Absolutely shocking service from call centre agent Makoena Ngobeni . She knows nothing about customer care . She called me to try and retain my business with them only when asked what my options are , she cuts the call on me . I called back to speak to the Customer Service Supervisor Mr Zontle Masilela . Only to be told that he will invesigate this matter . Im still waiting for someone from ADT to get back to me . Shocking service ADT . Train your staff to deal with customers in a better manner .
