Negligence

Good day

I have been trying to reach absa regarding statements on my cheque and credit card and have been pushed from pillar to post. Latest is I am told the account for cheque account is with Nimble group but according to them the account is at Absa since May. I have called all day yesterday as well. I will not be paying this account and will be referring this negligence to ombudsman. Please email me if you have queries.
