No feedback to resolve problems

I contacted FNB originally on 4 August to close my credit card account.Since then I have experienced numerous problems in attempting to close my creditcard. <br> <br> I contact the call center various times to follow up on the matter, as no one is coming back to me regarding the problems I have logged. The first call made on 06 August, when I spoke to Gloria. She provided me a settlement amount which was incorrect.11 August I received an email regaring the faulty settlement amount.I email again to find out why the settle amount was incorrect. Again,no one made contact with me to resolve the matter. <br> <br> I call FNB on my own expenses. On 13 August I spoke to Ivan, who said he will forward my query to Yvonne who is managing my problems. No feedback was obtained from either of them. <br> <br> 0n 16 August I go the FNB branch to resolve the matter. They are not able to assist me as I need to contact the credit card division telephonically. On 17 August I contact FNB again.Due to technical errors my card cannot be verified.The call center agent request that I send an email. The email was sent and by close on business 18 Aug no feedback was received from them. I am done! Closing all accounts !!!!
