Collections didn't remove hold!!

Firstly I must say that I am highly unhappy, I've been constantly calling the Nedbank call centre and being shifted from pillar to post over the last two weeks because of the hold the collections department has on my credit card!!! Today was just no different. I'm using my airtime every week calling them only to be cut off or consultant drops the call or I just never get the assistance in need. Anyway, this is regarding my Nedbank Mastercard Credit Card which was supposedly put on hold by the collections department without reason to me, when I did eventually get through to collections, they had advised that they did remove the hold and that I should go into a branch to get the account reactivated. To my disappointment yet again, I was told when I went to the Cresta Branch that they can't do anything because collections have not done their part and that I have to call them the Monday 18 Jan as they don't open on Sundays. Now this is the last resort as no one seems to want to assist me with this.
