Extremely Poor Communication

I’ve had a terrible experience with Absa. It took them over three months to resolve a credit card ***** case in which the communication was extremely poor. Almost zero. No one communicated with me about the process nor the progress of the investigation. Now I have a different person from Absa calling me at least twice a week hounding me for interest and bank charges on a card that is inactive. Yet, no one responds to my emails or calls me back to help me resolve the matter. Not even the investigator that was handling my case. Very frustrating.
