Store Card Blocked

My Woolworth's Store card has been blocked due to an unknown reason. Staff members can not give me a valid answer. The Client Services Department said they can not assist and I need to go into a Woolworth's Branch. Woolworth's' in the Mall@Reds said I should call Client Services as they can not assist. Please could I get feedback on how the activate my account. If this is they way that clients are treated then they should rather close their doors.
