Vodacom Service - Unacceptable

Called Vodacom on 3 August 2017 with an Upgrade issue - spoke to Siphokazi , Ref Number ********** ********** - 3rd party upgrade was done after a Sales call without proper information regarding the upgrade- I requested an immediate reversal. Called again on 23 August at 08h45, spoke to Phindla who confirmed the upgrade was reversed on that specific number and i could upgrade again. I asked her for the complaints number. The number she provided is not a Vodacom number The Upgrade due still does not reflect. I called ********** number only to hear that the upgrade was now due in 2019 July. I want this resolved as i'm sick and tired of this service I have been a customer for over 12 years and this is not on . Really unacceptable ........
