Absolute poor customer care

I closed my Standard Bank account last month (April) and called homeloans with my FNB account where they are supposed to start deducting. To my surprise, the day for deduction (25th April) has come and gone without any deduction from my FNB account. I called Standard Bank to ask why they did not deduct- to my absolute horror I get told that they tried deducting on my closed account?? The account was closed at their HATFIELD branch and I was given my meagre balance of R120, now I get told the account is not EVEN CLOSED! What the consultant I spoke to heard when I changed my account details was that I am increasing my debit order amount? Really? And I will have to make a manual payment before they can load my FNB banking details (as they cannot load if account is in ARREARS)? Whose fault is this by the way? I had to be put to CREDIT rehabilitation for a new account update- (my account has never been in ARREARS before this MISHAP) I hope this time it will go through? HOW SERIOUS IS STANDARD BANK ABOUT CUSTOMER CARE? ?? Clearly the fact that you have to call, use your airtime and TIME, does not matter to them??
