Disappearing data STILL AN ISSUE

I logged a call on Sunday, 27 Aug 2017 at around 17:00 regarding rapidly disappearing data. I spoke to a call centre agent called Glenda, whom logged a call with reference number 1- ********** ********** and was told it could take up to 48 hours to resolve. I had to disable my mobile data as I cannot afford to be loosing data, then any available airtime in literally seconds. I followed up on the query at approximately 16:45 on 28 Aug, and spoke to Guilette. Who first told me I didn't have access to the internet as I had no data... I asked to be put through to the technical department to get an ETA on resolving the issue, and was cut off. On Tue 29 Aug, I again loaded a 40MB J4U bundle to test the data consumption. Within seconds the 40MB were gone, as well as the remaining R13 airtime I had left. I called again and spoke to Nicole who graciously dealt with my anger and frustration and gave me a credit of R29. She also returned my call this afternoon but was unable to deny or confirm that the disappearing data was still an issue, or, to confirm where my data was going to. I had to end the call before I lost my temper... again. I am in the meantime unable to reactivate my mobile data in fear of any possible airtime going missing again, and thus rendering me unable to use my very expensive phone - and this while most of my day is spent on the road. It is now nearly 48 hours and still no word from Vodacom... am I expected to wait indefinitely until they are able to solve this much publicised issue???
