Refused payment arrangement after your incompetency

Just received a call from a very rude Anele Phiri seemingly to attend to the query I raised sometime back. To my surprise she called me with her system (DM9) down and could not even confirm if my query is resolved in terms of them debiting my account on the 25th of every month and or debiting the Friday before if the same falls over the weekend – this defeats the entire purpose of her calling me when she can’t resolve or at least have a view of my initial query. Secondly the insists that she cannot breakdown the outstanding amount over a couple of months since the error and incompetence was on your end where you did not follow the mandate that we had agreed on. There is no way I’ll be able to pay the full outstanding amount once off in full, I cannot agree to be inconvenienced by yourself for the error on your end that I tried to rectify multiple times with you failing dismally – as it stands I will be referring the matter to the bank ombudsman to look into your inability to break down payments for your clients due to your incompetencies.
