Bad service

I have a credit card with woolies which it supposed to debit on the last working day of the month but that's never a case with them my first debit it went out on the 1st instead of the 31st and the 2end debit it went out on the 2end of October which it even bounced I don't know how because the was money in my and the SMS I received showed amount debited and my remaining balance in my bank account, I received SMS saying I'm in errors coz of the payment not paid I should make a payment to avoid collection. Why do you wanna charge me penalties while your the one at fault, you choose your own date to debit on its not like a reversed debit now I'm getting charged left n right for your mistakes, I called your call centre today to query about this charge I spoke to the lady by the name of Raheesa Adams I requested to be removed from debit order so I can pay via EFT to avoid the late debit I was told its not possible since my account its not up to date I need to make payment the agent was so rude as she kept on telling that she won't keep on repeating herself because the is no solution here when I say I don't have money now to pay the errors and I can't afford double debit, she didn't even fix the problem on the system of late debit, what's the use of giving us ur queries number if your agents they don't wanna help they talk over us even rude where are we supposed to direct our queries
