Unhelpful Call Centre Supervisor

I would not even give Tracker an half a star. My father is a pensioner and cannot use all his airtime holding the line for a call centre to help him with an debit order issue. I called on he's behalf to sort the issue out. First out you are meet with the most self centered people. Spoke to a Lebogang that interrupts you. Yes I gave her a piece of my mind. 3 hours later my father let me know that Tracker have not called back. I call again ask to speak to Lebogang, oh my word the attitude that I receive from that "supervisor"! It is unbelievable!! I would like a MANAGER from Tracker to contact me via email within the next 24 hours or else I will tell my father to cancel his contract with Tracker and move to Cartrack, who's recovery rate is much much better than Tracker.
