FNB Homeloan = Disgusting!

I am a very livig FNB customer this morning. Earlier this week FNB contacted us to say they had system issues with their debit orders and that we should please make a manual payment for our bond. I have done this the very same day. I called FNB Homeloans and they assured me that the transfer I made is sufficient and that this debit order issue from their side will not affect my credit record. This morning I received an SMS where they AGAIN tried to debit my bank account, the debit order couldn't go through because I did not have sufficient funds as I already transferred the bond payment. This now reflects negatively on my account and they have the audacity to charge me R110 for the returned debit order. I called them again this morning and couldn't have a decent telephone conversation because their telephone lines kept cutting me off and they cannot call me back. It is so sad to be left with this pathetic service until our bond is paid up!
