Service is pathetic! You owe me money!

I logged a data query over a month ago-Data was being used excessively & I kept reaching my call limit in the first week of the month! It was discovered during a phone call with a customer service agent that my normal package data bundle did not kick in, neither did my recurring bundle which I had loaded, neither the ad hoc one I had loaded - although I received SMS notifications that it had been loaded successfully. As a result I was charged out of bundle rates for the data usage on my phone and kept having to load more bundles, and naturally my phone kept reaching its call limit prematurely. This was over a month ago. I have contacted Vodacom Call Centre on numerous occasions since then only to be told each time the query is pending. After becoming angry and frustrated an agent told me she would escalate it and assured me it would be resolved. A week later - still pending! Now even more furious I demand to speak to a supervisor / Manager (Kelly) who promised me she would escalate it and contact the Manager of the relevant department directly, and promised to call me back the same day. Still waiting for her call. Today after being put on hold for 20 mins I got cut off! Furious!
