E-TOLL AGENTS OBTAINING INFORMATION *********Y - ***

Some one from value added services called me in regards to update my details for e-toll, when I refused to give my details. she called me at my work posing as someone that have a parcel to be delivered for someone at my work address, and I need to confirm the company name as well as the physical address. at my work place I can see the incoming numbers that call, and noticed that the number that called me on my cell phone requesting the info I did not give them, just called me on my work phone posing as someone else and lying to get information. I think this is very very very un ethical and sly from e-toll and voip South Africa.
