Harassment by Vodacom and ally..

I herby put it on record that Vodacom, outsourcing another company (012) area phone code, harassing me almost daily.. l firstly politely asked to remove my contact details from being targeted but falls on deaf ears.. Now once l answer and question the calls agents drop the call in your ear.. Harrased and rude behaviour.. Vodacom l’m certain will insist it not them however l made it clear when l switched to an another network, a year ago. I’m still being pursued..
