Poor technical service

I have beem a vodacom customer for as long as I live, but let me tell you lately there is nothing that can irritate you like the Vodacom network. whenever you want to call for example and you have airtime, you will first get errors that you do not have enough airtime until you try for the 5th or 6th time then the call will go through. Today I have R9.99 airtme and am trying to buy 200mb for R5 and it keeps on saying I do not have enough airtime when you try on the app it gives an error that the transaction could not be processed. do better please or close down the network then we will move to other Networks. Imagine if you are in an emergency situation?
