Cell C messing customers around

Cell c contract department don't seem to know what they are doing. I've called on two separate occasions to get the monies for my contract be debited from one account to another. I signed the contract with cell c on the 30/09/2019, two weeks later i called cell c contract to change the debit order account as the account in question is specifically open for the purpose of having monies debited from. Initially on signing of the contract i opted for my Capitec account to be debit from, i was told that i need to give the account in which my salary/wage is paid into and that was the account we gave (FNB).

It has become such an inconvenience having this cell phone contract as the monies keeps being debited from the wrong account as it at times doesn't have funds in and affects my bank account into negative.

I called again recently after being inconvenienced after all these 9 months, i thought id try once again but witht the hope of getting helped from someone who actually knew what they were doing. I went through the same process as i did the first time; security questions, giving the the new account to be debited from, also confirming debit order dates and we get confidently told "everything has been processed"and ****** being asked to rate the service under the impression that your request had been fulfilled.

This morning i have just received notification the cell c debited the monies from the flippen incorrect account (FNB) once again. This just indicates the lack on competents within the department.

I need this to be resolve immediately as still cant continue to happen. this is extremely frustrating.
