Inconsistent treatment and unfair changes to my access facility

Capitec deducted the monthly revolving loan amount but same has not been directed into my account for access. My understanding is that a revolving loan gets deducted then funds deposited into that loan account, but that has still not been done. Why this time around? Again, the bank reduced my access facility to R 90 000 and I did not ask for this. I want my facility to remain unchanged. I don't understand why this was done without my permission.
