Account Closure, ITC Update and Paid Up Letter

I have settled my Credi Card in full and have requested a paid up letter since Thursday the 7th of July with no luck. Spoke to Nomsa on the 7th of July, she was very helpful. Spoke to Frieda again on Thursday who advised that I should send the proof of payment , request for Paid Up Letter and ITC Update to ***, have done exactly that. Received a delivery note confirming my email was delivered successfully and a read receipt but still no response from them since the 9th of July. Spoke to Milton today at about 11:35 and was reluctant to even try and go the extra mile. I have asked him to please put me in contact with a manager for further assistance and he said he cant do that I will have to wait for a response on my email. I said ok Milton so I guess I have to logg a complaint against ABSA and his response was yes mam. I find it very frustrating unprofessional to say the least as I'm in the banking industry myself and have never came across such bad service. What a disappointment Credit Card Legal Department!!!
