Horrible Vodacom assistance

Someone from vodacom rewards company called me and gave me two new contracts on top of my existing contracts on my name. So my monthly bill will be much more than i have budget for. This person then told me that i could transfer that extra airtime to my number sp that i have more airtime and a new phone. I confirmed this and the phones arrived at my home. I went to a vodacom shop and the consultant told me this in not possible to do this. I then called to fix this and i talked to someone very high up in vodacom and he said that its fixed and i can transfer the airtime. This is still not posible and this has been going on for 3 months and no assistance from vodacom at all. Every one i call and talk about this put the phone down in my ear. The future is not happening if the online department is not helping if i have queries. Please someone help and assist.
