unable to stop their spam (that I didn'tgive permission for)

I discovere after porting my number to vodacom that without my permission they opted me into every single spam program they have AND shared my info with thirs party spammers. opting out of everything is intentionally painful, drawn out and error-prone. Dear Vodacom, here is a cover all before I go to the ombuds : STOP! And make sure you didn't *******ly sell my info to anyone because that breaks several international laws
