Vodacom dishonest & unhelpful

I keep buying airtime at Vodacom and it keeps disappearing, was told to put a 0 out of bundle restriction which I did but airtime kept disappearing. Every time I recharge there’s a dispute. Same things happened yesterday using the free airtime, my actual airtime disappeared while I still had a balance on the free airtime. I called Vodacom and Khanyisile put me on hold and then after holding for a while transferred the call without telling me. The next consultant had an attitude telling me I don’t have proof & I should’ve called yesterday when it happened. It became ugly as we were now arguing and basically telling that how do I expect her to fix when I don’t have proof. I told her she doesn’t have to if she doesn’t want to and then I kept quiet. There was silence for almost a minute without any solution and she just said is there anything else , I said no and she just said goodbye. No help , waste of my time. My solution is to leave Vodacom.
