With them for 20 years and treated like a no body

Firstly I would like to say....that I know this happened in my error! But hear me out!!! I have been with fnb all my life, they make a great deal of money off me and treated me like thrash after so many years. My name is very important to me and my rating with the bank and ITC is excellent but after 3 debit orders that went unpaid last month I am devastated and truly disappointed with fnb. I have recently changed jobs after working for a company for 17years, my salary was always in on time and debit orders always met. I have changed jobs now and battled to get everyone to debit me on my new pay date, especially not work in an office and having a telephone at my beck and call. Fnb has always honored my payments knowing that there will always be money coming in and that's how it went for a couple of months but last month without ANY warning they let 3 debits go unpaid, I was devastated and hurt that they wouldn't even call me before it happened to tell me that they were just going to let it go unpaid after them knowing that I have 3 investments with them and clearly seeing that I do have money. If they alerted me I would have made sure there was money in there. So Done with FNB:(
