POOR SERVICE - BROKEN PROMISE NO 4

This is my 4th Complaint with Cellc regarding my contracts. i recently upgraded 1 of my Cellphones with the contact centre and this time there were no issues with the upgrades department, they was friendly etc. i called Cellc on the 15/02/2016 and cancelled my BIS subscription as my previous cellphone was a Blackberry and i have upgraded to a samsung J1. when my contract came into affect i was billed almost double my installment on the first month , according to consultant Zanele Nanyike, my contract is R117.00 but i requested for the recording of my contract because i know my contract is R99, which is what i was suppose to be billed. but i have been debited for R191.00 even if my contract is 117 let me hear my recording to confirm and confirm that i cancelled the BIS and did not want to be debited, as she could not explain anything she gave me the headoffice number which i spent 11:18 mins of my own airtime calling to speak to Mbali Maziya who confirmed that i was incorrectly billed, that i cancelled BIS, i made this call on 01/03/2016 today is 07/03/2016 i was promised that an agent will call me in 48hours to resolve the matter im still waiting. Such lies ! Ref no: ***
