poor service

I have a credit card with Nedbank and today I tried getting a limit increase, it was declined because apparently I am under debt review. My husband went under debt review in 2012 when I went to Varsity. After I completed my degree in 2013 we cancelled the debt review. Nedbank granted me a credit card in 2013 and now when I apply for a limit increase I was told that U am under debt review. I tried calling the debt rehabilitation centre, but Deneo whom I first spoke to was unable to assist. I called back for her supervisor and I was on the line waiting to speak to a consultant for 45 minutes. I did not succeed to speak to anyone to sort this mess up. My husband has repeatedly tried to sort this out with the bank, but no onevis willing to assist. I am very dissappointed with how this matter has been handled. Poor, poor service!!!!
