BAD SERVICE - STILL NO RESPONSE

On the 30th of June I complained about an OBF Rejection as well as shocking service. Vodacom called me the next day and said the query would be investigated and resolved. I saw they called me once but I missed the call. No further emails from the store, vodacom or anyone. No calls to follow up. Nothing. All I am being told (When I again had to follow up and enquire) is that all avenues have been exhausted. I have read up on this site and see that this is a common issue with vodacom. I have had this contact for 6 weeks and only had the phone for 4 days. This kind of service delivery to clients is totally unacceptable. I cannot begin to express how absolutely appallingly I have been handled. It is shocking that service providers think that this is acceptable service and that clearly no one actually cares about resolving the issue. What do we as customers then pay for??
