Dis-Chem fails to protect customers private data.

Dis-Chem are more than worthy of a zero rating, having handed personal data (names, cell numbers and email addresses) over to a 3rd party who then appears to have failed to provide an adequate firewall to protect the data of 3.7 million customers and is now according to Dischem the victim of a data breach, so 3.7 million customers have their private info out there for every ***** on the planet to view and use. I would like to know when did I and the other customers give Dischem permission to hand my data over to some 3rd party?????????...... isn't it time to start looking at a class action against Dischem and any other party involved, Dischem's failure to ensure that our data is safeguarded is totally unacceptable and its time we made them feel the frustration of its customers.
