Cannot resolve upgrade issue with Data Bundle

I upgraded my contract on the 3rd of April and since then still have not received the 30GB once off bundle. Phoned 135 every day just to get a new 'escalation' reference number with feedback that the 'previous agent logged the query incorrectly' and the with the same promise every time that the bundle is now loaded and will be active before the end of the day. Further have I also sent and email to their customer service box and only received a response after 3 day but only to ask for some verification details. Logged queries online within MTN Active profile without response, 2 posts on MTN Facebook profile which only receives the generic response 'sorry to hear about your problem but sent an inbox message' which coincidentally I have already done with all the information, reference numbers, history etc. Every now and then I get an SMS to say ref ***** has been successfully resolved and the I call them just to get another reference nr. 7Days and no resolutions !? How pathetic can it get ? This is ridiculous !!
