Leaking personal information and ********** transactions.

I've been with vodacom for about 13 years, and had a fairly good experience with them. Until now that is. Apparently Vodacom gives out your personal information to what the call is "promo" companies, what we like to refer to as span callers. And one of these promo companies issued upgrades on numbers on my account with out my knowledge or permission and they expect me to pay for these upgrades. This is absolutely unacceptable. I called client services on the 27th January 2020 to find out what is going on. This is when I was informed that the upgrades was issued by a promo company. After been put on hold multiple times they transferred me to said promo company. And all they said they will have to do a investigation that will take 3 to 5 days. It been over a week and no one contact me regarding this. And I'm being charged for services I did not apply for!
