Vodacom sucks

I loaded airtime on 26/07/2018, sent an sms & made a call that lasted 3minutes 30 seconds. I then checked my airtime to find that the consumption was questionably to high. I dialed 111 (always used for Vodacom) and the voice guide advised that I had a subscription that was using up my airtime. The system prompted me to select 1 in order to cancel subscription which I did. The voice guide further gave options available & I selected to speak to an agent - Sibongile Mchunu answered my call and I relaid my strange consumption to her & she asked to call me back after investigating. As promised, she called me back and stated that my airtime was consumed normally and advised on the billing option that I was on which I asked for her guidance to change to a per second billing and she guided me accordingly.

I further informed her about the unknown subscription as mentioned above to which she responded to say that the vodacom system doesn't show her any records pertaining to that. I told her that there is no way that a vodacom voice guide can advise me & prompt me to cancel a subscription and even have an sms sent to me confirming cancellation but not have records of same. Sibongile insisted that there is no such information. I told her that I had googled the subscription (Sonxxie) & found that many people had complained about it as ******* & not communicated by the service provider. Sibongile turned so rude & impatient to a point that I asked for escalation channels with my query to which she responded by saying Vodacom has no complaint department nor channels to escalate. She later advised me that Vodacom does no longer use 111 in the first place (though I told her I had always used this number) and that Waspa is the company I must send a complaint to about this. I think Vodacom is simply unprofessional as represented by Sibongile & for failing to provide me with the history regarding my subscription. I need records of when and how this subscription came to be, any other subscription linked to my line and details thereof. Vodacom to advise as to why they have no complaint escalation department.
