Unfair treatment with my credit card

Absa jumped on my case after Hello Peter . They put me through to the complaints department which does nothing but try and prove how wrong you are . The guy assisting me told me it was my fault despite me trying to contact them so many times and getting a consultant saying my system is down or slow or other excuses . Account handed to Legal, no formal communication, emailed for someone to call me and bank emailed me back , no effort from their side . Had my cheque account closed because of be same thing . Charges just come up and u struggle to contact absa for an explanation. My wife had l have successfully moved to Nedbank and it's amazing and they have actually gained good portfolios and we will get a bond with them instead .
