******** got my cell c contract info

Been getting a few calls from people claiming to be from cell c. Got all my personal details asking me about banking details and so on. Very suspicious. Anyway, I know it’s not cell c, but the information they have is from cell c. I know this because cell c always mix up my first and second name, and so do these people. In any case, it seems as if someone has got hold of a lot of customer information from the cell c database without permission. Either a hack or more likely an employee has leaked or sold it. I just want to make people aware that this is happening so that either cell c can do something or the customers are aware that this is happening.
