Account and card enquiry

I tried to use my woolworths store card twice at Mall of the south and at Centurion mall and I have been told that it is not working. The Centurion customer care called the finance departed and was told that the card has been cancelled due to suspect of *****. I was then told that an agent from the ***** department would call me and a new card will be sent to me. Till today from beginning of August I have not been called or received a new card. I even sent an email to *** to inquire about my issue but have not received any feedback. what am I supposed to do now?
