CAPITEC UNWILLING TO CHANGE DEBIT ORDER DATE

And there it happens again... I work for a private company and my salary gets paid via EFT. My employment contract states I get paid on the last day of the month. However my boss try to pay my salary around the 27th or 28th already. I bank with ABSA and my employer banks with FNB with the result that my salary don't reflect in my bank account immediately when paid. Capitec requests the monthly debit order for my loan to be collected on the 27th of each month, sometimes even as early as the 24th, depending on which day the 27th falls. This results in unpaid debit orders from Capitec on my ABSA cheque account. Capitec representatives had phoned me numerous times on the morning of the 27th of the month, claiming that my account is in arrears because of this. (Need I say the 27th is still the 27th till 23:59 the evening of the 27th... Each time I tried to explain to them my situation. Nobody seems to be able to help my to change my debit order date to a later date like the 29th, just to make sure my salary actually reflects when the debit order gets collected. I am so frustrated. Is there anyone in Capitec who can help me? This issue is reflecting negatively on my credit record. I've never skipped a payment. All I requested was for the debit order to get changed to get deducted 2 days later, on the 29th of each month but this seems like an endless battle and in the meantime I look like a bad payer. Not one of my other debit orders bounce back because these companies actually listened to me when I requested for their debit orders to get deducted at the end of the month. It's just Capitec... I must say that I haven't had a good experience with Capitec at all :-(
