Non Receipt of Data and SMS bundles

I did an upgrade in March 2015 and since then I have not received my Data or SMS's. This is ridiculous as my account is debited every month without fail. I spoke to Saajidah Gafieldien on 22 May 2015 and she assured me that this would be resolved by 25th, when I called her now she just said its been logged and been escalated to Head Office it will take another 48 hours. That is disgusting and absolutely absurd as it should not take days to resolve and besides trying to call MTN is an unbelievably hard task as no calls are being answered. Why should I be calling Head Office and especially since she knows we don't ever get through.
