Vodacom *****ing money

For many contracts I have gone from uchoose flexi plan to another uchoose flexi plan as Vodacom call centre said that you don't lose your balance of airtime and I never have. Now they change the name of the plan to uchoose flexi 202 from uchoose flexi 165 and take R995.91 airtime away WITHOUT notification. The sms said that it was just the name change. The query was escalated nut NO reference number has been given to me for this. Having just had Vodacom be part of a ***** on my bank account( they deny culpability even though my line was blocked by Business solutions and they now don't answer my calls, emails or hellopeter complaints regarding the shirking of their responsibility the responses have not been followed no calls to me) and now they ***** my airtime I am VERY angry. I need action.
