Absa reluctant to cancel my credit card account

Customer consultants were unable to assist me in the branch with cancelling a credit card. They signed me up for a credit card with ease, but cancelling is a tedious endeavor.

I only used my credit card for international travel and no longer require the account. They are reluctant to assist me in this matter and told me that someone will call me to discuss the matter.

I simply want to cancel my credit card account and their terrible customer service frustrates me to the core.
