Contract for my cell 0649060676 changed without my authorisation - Consumer Complaint for Vodacom - Head Office

complaint about the migration of my cell no in December 2019, I did not request such migration. The main number 0827714764 and 0649060676 are on the same contract, therefore if I make changes I will do it to both numbers.
You promised to come back to me about this matter, am still waiting for more than 2 week
