Very poor customer service received

I would like to express my disappointment with the Absa Life call center agents, I have attempted three times already trying to Amend my existing funeral policy and I always get the same response, "there is an error with the Absa system" and always promising to get back to me regarding this matter but nobody really cares to get back to me as an Absa Client and I'm beginning to doubt the Absa organization holistically if they should be trusted to do banking with and clearly my story does not matter to Absa Bank. Can somebody please intervine to this matter with urgency before you loose my business.

Regards Mr M Mhlongo
