FNB - Premier Credit Card Division needs a month to close an account no longer in use

On 3rd July, I requested that my Premier Credit Card account be closed so that it stops reflecting on my banking profile after I upgraded to Private Clients. Case number CAS- ********** -J7Y6G0. After receiving no feedback, I asked my banker to action the request on 10 July. She escalated the request to the relevant division however after they did not provide her with feedback either, I sent another email request on 20 July to close the Premier Credit Card account. Reference CAS- ********** -J3Q8B0 and CRM: ********** ********** 3. Still waiting. As a Private Clients customer, this level of service is unexpected. Premier Credit Card division - kindly close the account and spare me the horror of waiting a month for a redundant account to be closed. Fnb
