Vodacom Customer Service -inept and tedious

I need to activate International dialing on my contract. Called Vodacom on 082 111 yesterday morning 9am and after 20 minutes was assisted by a live person who advised would activate the service and how to self help to get cost friendly option. Followed instructions and got a message to say not activated for International dialing. Called customer care again / eventually the call was answered and the person then repeated the original process and said it would take 1-6 hours to activate. Yesterday evening called customer again and was advised I had been activated according to their system and the fact I could not utilize the service could not be escalated for 24 hours after original call. This morning at 8 I called again and the operator escalated the problem and advised Vodacom would call me back within 2-8 hrs. At 10 pm when I called again was advised by the operator that they have a record of my escalation but it hasn't been attended to and it cannot be escalated further as 48hrs hasn't passed. No contact number for complaints-no higher authority to speak to- No service -no recourse-just wait for time to pass so we can escalate again?? No hope for a solution.
