Frosen Account

For almost 2 month now,I cant use my card for withdrawal or purchasing and from the branch level up to their call centre,no one can explain or able to resolve my problem and I beginning to get tired of this. Firstly my account was frosen without any communication or warning towards that,only learn of that through one of the most embarrassment I have ever felt in my life. It was after having done my shopping at shoprite and when trying to pay by card,it kept on declining and this past Saturday went back to the branch and still the matter is not resolved.
