poor Customer Service, Exploitation and lack of Help

If I could I would give them a below 0 rating. I contacted them for assistance with changing my account number for their debit orders as I no longer have access to the one they have and mainly because there would be no funds to debit. To which the response I received was that was not possible as the account I wished to provide them with is not 3 months old. Having heard this I asked if they could cancel my debit orders and let me pay them electronically or via their online portal up until the account I’m using turns 3 months old and even this was turned down saying I would have to make payment 10 days prior to my debit order date of which is and was impossible as I did not have that kind of money and would only have it on my pay day. Having stressed this I was told to make payment via the app portal and that a note would be made for my account not to be debited as there’s no money nor do I have any access to it. Yesterday I get my new invoice to my shock I’m charged an exuberant amount for the debit order bouncing, a debit order I had called in about +-10 prior to the date to stress my situation. I called in immediately and spoke to a lady then to a guy by the name Thabiso who were basically was of no help to my situation telling me they cannot add my new details nor cancel my debit order and should make payment 10 days before my debit date or opt for a payment plan that will render me without any connection for the next 3 months or simply accept that I will be paying an exuberant amount up until my bank account is 3 months old and can be accepted by their system. As I type this I feel angry, exploited and not taken seriously. Basically I will be charged high amounts of money for failed debits orders running on an account I have no access to nor can I put money in as the bank with take that money cause basically you refuse to help me for your own selfish gain
