Payment break affected my credit profile badly.

i was offered a payment break for 3 months on my credit card, but i still paid on monthly basis even though it was not a full installment, last week i app**** for a vehicle finance and i was told that my credit bureau shows that i am 3 months behind with my Nedbank credit card payment, i tried to explain that i took a payment break for 3 months but they told me to take it up with Nedbank because they are the ones who supply credit Bureaus with the information. why would Nedbank offer us a payment break if this is going to affect my credit profile? and anther thing the payment break ended in October but my account is still frozen, i tried by all means to get it unfrozen but its not helping.
