ZERO regard for entrepreneurs' growth!

I am extremely annoyed with FNB, I have been with the bank for over 15 years and it is finally time to move on. Apart from other bank accounts, I have had a business account with FNB for almost 2 years now and almost added the pre-approved private banking cheque account... Every single time a debit order does not go through I get charged a fee which is more than the amount that could not be debited - HOW ridiculous?!! FNB would rather deduct their account and service fees before honouring a debit order that is set for the same day, taking more money from my pocket at the end of the day. The exact same thing happened yesterday, I made provision via deposit for a debit order that had to go through, this morning I get numerous failed collection smses, upon logging into my banking app, I realise that my account fee was deducted, along with service fees that is almost as high as the account fee (the service fee being the highest is has ever been), PLUS a failed debit order fee!! I don't care how the systems are setup and what perfect excuse there could be for this.... Why not honour the debit order first, then have the account go into a minus with bank charges until another deposit is made to cover it?!! I am honestly done!! I always let this slip because I do not have time to phone in and query this nuisance of a business account but no more!! FNB has ZERO regard for young entrepreneurs, really disappointing business banking! I am extremely sincere and have given this ample thought, I want my business account closed immediately. I would rather go with another bank for my business then be ********** with my eyes wide open. Please do not try retain me as a customer - I just want the account closed and that is it.
