Not happy with the service

So I was in arrears with Call direct due to being on maternity last year. I made arrangements to pay an extra R200 every month which I did. Now early in this month of November I switched banks and the bank was to arrange for my debits to change which they did. I then received a sms saying and I quote "Unable to process Direct Axis debit order, service provider won't accept instructions from FNB." Then I called Direct Axis and asked them why not and I was not happy with the answer. I even asked for reference number to what I was told they don't have reference numbers. Really? Anyway we then arranged for the debits to go off on the 25th also I was to pay my 2nd last of my arrears amount which was R604 + R223 of which I have the confirmation letter. Low and behold past 7 Friday morning I get another call telling me that I am in arrears and that I need to pay my full amount after me explaining to this lady of the previous days arrangement she insisted that I have to pay the full amount. Me getting irritated but not wanting to waste anymore time tell her you know what just take the full amount. Didn't get any confirmation from that conversation.

So now pay day arrived over this passed weekend and nothing went of, I told myself maybe they will deduct on Monday. Once again nothing happened. Now this morning I get a SMS saying : "URGENT Dear MRS NATASHA RUSHIN. You did not adhere to your arrangement with CALL DIRECT. The full arrears of R1004.34 is payable immediately". So now this is my problem.

Then I called explaining the story of last week and I'm getting very angry as I'm at work and knowing I made arrangements for this with 2 people. I spoke to 1 lady she transferred me to Ferdouse/ Feroza not sure. Now I'm talking to her in frustration explaining to her my situation and I'm getting a bit high toned but it seemed as if she also raised her tone but I remain the client. After realizing she won't be able to help me I asked to speak to a Manager she 1st told me that he was going to tell me the same thing etc. I still insisted. I then spoke to a GUAN not to sure about the spelling. She explained to him my story . I was then told that FNB was not allowing them to take the money then I asked for him to send me rejection message in order for me to confront them to which his answer was he can't due to company policies. Like how do I confront someone with no proof. I insisted he refused. I also asked that can't I just make a transfer and I was told that they would still want to make the debit this was said by the Ferouze lady. I honestly don't have the time to run up and down, I have work to do and want this to be shorted. It's not like there is no money in my account.
