Vodacom deception again.....

I am completely over all the nonsense that Vodacom is giving me. The final straw has been my airtime that, according to the contract I signed is supposed to carry over. I have been a customer with Vodacom for more than 16 years. My phone was off from February to beginning of November. My monthly fee was being deducted as usual, for my hand set, data and airtime. Only to find it's not there and when requested, I was told I'm not getting it. This in my opinion is theft, there is no other way of looking at it. I'm really tired of this. A red contract was also taken out at just under R2000pm, with the promise of up to a 35% discount with the lowest being around 10% on all Emerits flights. The most that was offered was R500. Vodacom in my opinion is trying to trick it's consumers more and more each day Into taking more money and giving much less. I am not letting this one go.
