When an access bond becomes a non access bond.

Without notice and during the worst economic circumstances in South Africa ) January 2021) I have had my access bond transfer wiht Standard Bank Homeloans denied despite last month paying into my account a huge sum, wishing to draw on it this month. i simply cannot retrieve the money I paid in. Not once have I failed to pay the monthly dues. There was no notice for this action, and no negotiation is considered.
