Nedbank: Stay away!!!

So disappointed with Nedbank Credit Card division!!!! I gave my Wife permission to handle all my affairs. I am a sick person. My wife has never experienced such bad service after speaking to 3 different people today. They kept on transferring me to 3 different people!!! We need a Paid up letter that we paid Nedbank in full: Now I owe them R110 and cannot give me a paid up letter. On the 19th of August Nedbank refunded me R330. as an in experienced Nedbank personnel at Somerset West Branch gave me the wrong settlement amount. Now I owe Nedbank R110.00 . That is the reason why they cannot give me a paid up letter. I said to them stop putting me through to different departments and I need a explanation. the person was so rude and he hang up!!!!!
