Poor pathetic service on Prepaid

I have been a vodacom client for the pass 15 years my very first phone was taken out by vodacom and I have stayed with the network ever since then. Recently I having been having the same reoccurring issue with them as my data bundles do not work or data bundles I have paid for using my airtime cannot be used. I work in the IT department I rely on this to constantly stay in contact with my clients and updates within the workplace and this has turned out to be a nightmare for me. I have contact Vodacom customer care and what have they done nothing ,they have soft locked by phone from the Vodacom network I could not use my phone for 3 days and no again another 5 days this is happening every time I contact Vodacom I wait for hours for nothing to be fixed I should not be having a problem if I am a prepaid customer and all the airtime used to sort this out and also data bundles bought nothing is being fixed I sit with a phone that I still cannot use and data bundles I cannot use till today I am still not able to use either of the bundles I have available to me. What I have done is buy another prepaid sim card to use after years of being a Vodacom customer I think its time to change my Service Provider if this continues to end of the month.
