Can't follow requests, won't fix the problem

Due to the exorbitant fees charged by exceeding data bundle packages in the month of March I requested that the 1Gb package I was on be upgraded to a 2Gb... and again I requested the upgrade in April, May and June... finally in July the 2Gb package is loaded, and the fees charged by exceeded the 1Gb bundles over that period caused an outstanding balance of R2195.27. On no less than SIX occasions - telephonically and Two emails (off of the Vodacom website) there has been zero interaction nor support! In fact, the people that I have spoken to have offered me ref #'s: s3-8bj2q-q9v4h (20/07/15) being one of them. Some people that I have spoken to: 06/08/15 Thabiso Thamae, 12/08/15 Nokuthuala Phiri (puts the phone down) and Michael (??) simply forward the call to some nebulous number that never gets answered, and promise answers in 3 working days.<br> It is a simple solution, go back in the telephone records. Listen to what I asked for, see what was done (or not) and then let me know what is the situation in terms of the account balance. Against that it will be clear that the fees charged are due to exceeded 1Gb when 2Gb is what was requested.<br> After 1h04 on the phone, no resolution
