FNB bad service

I received an message from FNB that they have processed my debit order. I haven't even got paid my salary yet. And they proceeded with debit orders. Now it puts me in a bad light. How many times do I have to tell FNB that I don't get paid early in December. This to me is very humiliating. Coz now I have to get charged fees unnecessarily. Is this how FNB threats customers that have been a client with them for 27 years. Then they send you an email sorry for the inconvenience caused and I must put in a request for revearsal of charges. It's is unacceptable
