Nedbank personal credit card ***** department- poor service

I started contacting Nedbank Personal Credit card div on the 11th of April wrt ***** on my credit card. The call centre is useless! Either dropping calls during conversations, putting the phone down as soon as it is being answered (where you can literally hear the phone being answered and the call centre background noise- then ****ing it) or calls being unanswered for up to 35min. Every second day or so I have tried to contact them for assistance and investigation. No joy. This does not stop Nedbank to contact me all the time for new products, increases etc. During these calls I mention my problem and these consultants try and assist but the same happens during their transfers. The ***** call centre is useless and I wonder how many unhappy Nedbank Credit card clients have moved banks because of this poor service. 2 weeks ago I managed to talk to a very kind lady called Clarissa Hoffman who took the time to email me a Cardholder transaction dispute form and given me an email address to which I should email this form. This was done, on the 11th and no email or call back confirming the email was indeed received by ********** Certainly Nedbank Personal Credit Cards can employ more consultants if man power or dedication to their work is important?? The Transactions I am ref too all ends with a .com and it goes back to Feb as I can see, Nedbank- contact me asap
