Car track ******* / unprofessionalism / poor customer service / consultant with no product knowledge

I called Car track clients service department as I wanted to downgrade from R265 package that is due to increase to R291 as part of the 10 % annual increase that I was never made aware of on the 23rd of Jan, the consultant booked an appointment with the technician to uninstall the old unit and install the unit for R150 per month with the downgrade service fee of R250. She informed that the downgrade fee will be debited from my account end of Feb with the new installment of R150, to my surprise I received an SMS on the 5th of Feb stating the downgrade fee of R350 is in arrears, I called them immediately and I was assisted by a rude lady by the name of Katlego Marumolwa that has still not provided me with feedback since the 5th , I also discovered that my new instalment will be R187 after I made it clear that I’m downgrading to R150, I’ve sent numerous emails, called over & over, requested to speak to the manager and guess, consultant (Katlego Marumolwa) would place me on hold for more 30 minutes until I ran out of airtime, it’s so amazing how professional and friendly their sales team sounds but once you become their client, you only receive poor customer service and *******.
