Unsolicited sales call / using my info without my consent

This morning received a sales call on my cell phone, for African Bank from number ********** 600. The person had my name and number details. When I asked where they got my information from, they said from my bank (which is not African Bank). I responded saying I had not authorized anything like that, to which the agent rep**** saying perhaps I didn’t realise that I had agreed to my info being shared. This is just one of a whole bunch of calls robocalls SMS’s etc I get, and decided enough is enough. This unsolicited contact and access to my info without my consent is unacceptale and additionally does not win any positive view from my side ito the company involved. If anything it would ensure I’d never use their services. 1 (slightly) plus point compared to most spam calls - the agent was professional enough to give me their name, and say where my info had (supposedly) come from. The agent is doing their job. The company is at fault!
