Poor Service Account Closure

I went to the FNB branch Cape Gate to close my FNB gold credit card account with remique koen.She said she will email the signed account closure form and call me with ref that never happened.The next day etc i have emailed FNB numerous times to close my credit card account and complain on the complain link on their website they don't call back or respond to any email u only get automated response emails.I called customer support etc and the service is shocking calls that gets dropped from one dept to the other dept
