Vodacom get your customer service back

I requested my late daughters number to be cancelled. No they will just place it on a prepaid will cost nothing and then the drama started. The prepaid now has a re-occuring what app bundle. Ok that I can still let fly but through this they climbed into my account (main account holder) on 4 November. Removed my 30Gb Data Package added a 1.2 Gb whatsapp package & just so I do not notice they gave me a 1 month 30 GB FREE. I never watch my data as I have more than enough but I started getting messages that I am now out of bundle rates so when I looked I discovered what had happened. I now have all my airtime depleted, no data & a whatsapp bundle. A total of 3 hrs on the phone multiple reference number & still no joy. How difficult is it to just put back what you took away & delete what you creatively felt I needed. I have been with Vodacom since inception & have not experience such a pillar to post system that still leaves me with an unusable account. REF *** even has pictures of my billing to make it easy to understand.
