FNB Home Loans - Failure

FNB Home Loans debited my bond payment late and now I am having to phone around to fix all my accounts that have been affected by their error. I send an email to their care division and I am still waiting for a reply. Why is this FNB error affecting me, it better not affect my credit score and why was there no communication sent out to say they apologies and they working on correcting the issue????? you have dropped the ball FNB Home Loans
