Data not loaded. No response from Vodacom

It is already 7/01/2016 and my data is still not loaded on 2 of my contracts!!! It is impossible to tell this to your machines that are handling the call centre! I also phoned Langeberg Mall vodacom and I am still waiting for a reply. This has caused me to loose a day of business because this is not the 1st time my data just dissapears. It has happened about 6 times now that data onmy wifi and 3G contract just dissapears at exactly the same time . I have been to a vodacom shop numerous times and all they do is tell me where I can check my balances. Well now I do check my balances and I can see when my data is not loaded or taken away! I have 4 contracts with vodacom but I am fed-up now I am considering going to another network as my daughter is with someone else and there is no problem. This has cost me again to by out of contract data bundle that is very costly! Very upset,!,,,
