Airtime and data disappears

I have phoned in about this issue multiple times. I will NEVER recommend vodacom to ANYONE. The past few months they have been taking my airtime and data and it just disappears. I load R50- It's gone , I load minutes on Just4u - It's gone and when I phone in (wasting even more of my airtime) they say "nothing indicates on the system as to where your funds have gone." Vodacom is expensive and I would not advise ANY person to ever switch to Vodacom. I was at MTN for years and eventhough they were a little expensive, I never had a day's worth of issues with them. Vodacom does not care about their customers and I cannot wait to get out of all the contracts with them to migrate back to a provider that is willing to help and FIX the problem at hand- not allowing the problem to happen over and over again.
