Vodacom customer, details leaked.

I just wanted to share a concern, please be very aware when complying for telephonic contracts with a company called RewardsCo, they are based in KZN and call clients on behalf of Vodacom, we did a request for a fiber line in January. This was later declined due to location and the service provider is not in our area. But the scare was when we were debited for a contact for MTN that we had not taken. Our information was leaked and a contract was taken via RewardsCo. This makes me question their system breaches as staff have access to clients accounts and it seems like they are used to commit *****. Been a Vodacom customer for over 17 years and have not experienced any issues before this. Vodacom should be vetting their service providers that they are entrusting customers with.
