Shocking Service lack of accountability!!!!!!

I am extremely disappointed at service received from Cell C Customer Services department. The quality of service received from their Call Centre agents are shocking, tone, willingness to listen to what the issue is. My problem that I faced was in August called them to say please change my Debit order date from 25th to 1st of the month as I get paid on last day of the month. In September, October and November I was still debited from my account on the 25th even after making another call. The retentions lady did not listen to the fact that by debiting that last money from my account left me in a predicament financially and I wanted someone in some sort of authority to call me as I wanted to be compensated from Cell C for the malfunction of their system that has put me in a difficult situation. I was promised a call and guess what a week later still nothing even though I said to the *********** staff member that I have a major problem with the current situation. The staff members that I dealt with are obviously not passionate about customer service, and should not sit in that space as they are giving a Cell C a bad name. Looking for someone other than a Retentions consultant to call me, someone in authority!!!!!!!!!!!!! Highly disappointed have contracts for over 12 years!!!!!!
