NCR giving Liberty Credit Solutions personal details of South African Consumers

NCR gave my details (Contact numbers, ID Numbers and everything) to Liberty Credit Solutions to call and inform me that I am one of the Consumers who are charged more interest. Once I asked the Liberty Credit Solutions agent to remove me from their database, I then received a message from Liberty Credit Solutions claim that I gave consent for them to receive my Credit Report. If indeed NCR didn't then they must investigate and deal with this Liberty Credit Solutions.
