Still Waiting for my Feedback

I am very disappointed about how all my Vodacom contracts are handled. I called Vodacom last year to confirm how much airtime I have on *** and was told its R500 the reason for my call was because I wanted the airtime to accumulate to R1000 so that I can convert it into DATA. When I called on Monday to confirm how much I have I was told R500 which I did not understand why as I had R500 last year. I was then told that if airtime is not used for well 1st they said 1 month than it changed to 6 months (as I asked if it was one month than why do I R500) it would be forfeited . My argument was that no one told me this. Call centre referred me to the store I bought the fone which they referred me to head office spoke to Batsiba and she explained well to me that the store manager needs to investigate if i was told and if not they would have to refund me she than referred me back to Century. I called century yesterday and was told by the manager that he would call me back i am still waiting. The treatment i received from Jozi was marvellous compare to Cape Town. All my contracts with Vodacom I have to fight for service *** and ***) every number I end up with a problem
