Never answer a call from vodacom /Mondo

If possible would give 0 stars for misleading old people. Why does vodacom give customer numbers to other suppliers like mondo, My mom got a call from Mondo, she is using vodacom contract this guy promised my mom data for R8 on top of the package she is getting. Boom on the 1st of December the package was completely changed now she is paying a lot of money. I called they said after investigation it was found that my mother agreed to a migration when asking for recording was sent to vodacom shop. I get to vodacom shop they say they can't assist with call recording. Why is it hard to send the customer the recording of the call been calling several time been told migration can't be canceled nor reversed but why, who gave you permission. This thing of taking a contract with Vodacom and being called by mondo its bull**** I must say. Advise people if you get a call from vodacom or mondo do not say anything because responding it's like taking a new contract
