Takealot security breach

!***** INCIDENT! I had a phone call yesterday claiming to be from Nedbank ***** dept asking if I made a recent purchase of R2800 from Takelot. I could hear it was a ****. They had my phone number, knew that I banked with Nedbank and that I am a Takealot customer. Perhaps also my bank account no? When I started asking questions they immediately rang off. I am reporting this because Takealot has clearly had a security breach and ********** access to their customer data. This is very serious. Takealot to advise what action you are taking.
