Fix your system!!!!

I've had my African bank account for so long, and in all the years I've had it, there's never been an issue with the debit order. For the past 3 months, the debit order doesn't go off, and then I spend the next week explaining to the consultants 3 times a day that the funds are in my account, I can even send them a statement. So since I'm being harassed all day, I just pay the account manually, while on the phone with the bank, from the exact same account the debit order is supposed to be deducted from. I've phoned African bank about this, I've sent emails, and I have to tell the same story every month. I get ZERO feedback from anyone at African bank. This is costing me a fortune in banking fees, never mind the hassle every month. This is ridiculous, where's the customer service???
