Bad online shopping experience

Payment was made to an online store. I phoned the credit card department as I received no response or tracking number. They say I can't open a ***** case since I made the purchase. I need to email the dispute department. I emailed twice, not even an acknowledgement of receipt of complaint. I stopped the credit card but feel that ABSA could of at least told me what I can do to stop these cyber ********* or tell me who I can contact. Surely they should have a verification system to authenticate a company before releasing ones money. Disappointed in their non existence of assistance.
