Never provide this company with any of your personal details - They will sell it!

After responding to an offer they advertise from MTN (Which I later realized never existing and which was used as clickbait) I started to get phone call from various companies. Its been less than 48 hours, and 6 completely unrelated companies called me for offers. I made them aware of the Popi act which came into effect on 1 July, but they didn't respond. This "phone"company also don't have any phone number where you can call them to tell them they should stop selling your personal information to third parties, because its *******!
