Banks don't look after their own

I logged a complaint with you on my finances behalf durbti the incompetency of absa as a bank and financial institution... The sms with the complaints reference was received and we awaited someone to contact him.... Was called your contact Centre as I was not aware that he'd be making a payment... SoAbsa failed to notify us of an apparent system change which resulted in my fiancés credit card debit not being deducted... He was not aware of this unt he received an sms and call regarding double debit order for March... He checked his bank statement and noted his debit order was not deducted which is a big issue... Cone a month later, he receives a call and sms... It is your responsibility as a bank to notify your customers of any system issues and that their payment was not received. It gives them the opportunity to correct the matter. This did not happen until now... We called your contact Centre and they assisted to a point but the call was cut before I could further enquire as his credit score and profile has been affected... We need this fixed as a matter of urgency. My fiancé received a sms tester stating his complaint is being investigated and not long after received an sms saying the complaint was closed... No call, nothing... This is not how a complaint is handed... I need some to contact me so I can advise on my Fiances availability as he works in retail and cannot always take a call.
