Requested new data bundle, charged out of bundle r

I refer to Call Reference #: 648992 - I called into the Autopage call centre on 15 April 2015 to request that a once off data bundle to be added to my account. The agent assisting me assured me that the bundle would be activated on my contract in 5 minutes, by the end of the day the bundle had not been activated. I called in once again and was assured by another agent that the bundle would be activated. On 16 April 2015 i called in once again because the bundle had not been activated, once AGAIN i was assured that by the end of the day the bundle would be activated. I had to call in AGAIN this afternoon (17 April 2015) and thankfully someone was able to add on the bundle. The issue that i have is that despite me requesting NUMEROUS times for the bundle to be activated it wasnt, and during that period my usage soared from +/_ R30 to R312, 69. I am nnoiw liable to pay for out of bundle rates because the 3 agents who assisted me prior to today were not competent enough to activate the bundle on my contract directly through the network. I refuse to pay for someone elses incompetence - please look into this matter ASAP and provide feedback as to how the billing will be rectified.
