Bad service

I opened up a credit card in May, debicheck was sent to my ABSA account. To my surprise I got a sms 2 days ago demanding payment no debit order took place I spoke to Keisha Anton who told me I need to transfer the funds. This mistake turns out not to be mine or my banks with double checking the debicheck I saw that Nedbank had the date as the 99th day of each month which isn't my fault I Just approved the notice without seeing the date. Now today I'm being called again despite Keisha fixing it to my salary date which is the 23rd of every month as per my application and the Nedbank app. I'm being called telling me I'm in arrears the account is behind not because I can't or won't pay it's your error if this negatively impacts my clean record I'll log a complaint much worse than this one
