No data

Having upgraded both my business data contracts to 10 Gb each for use in my routers I have discovered them to switch on for 2 minutes and then it switches off all the time. Its like its throttled down to nothing. I contacted Vodacom business to complain and they put the phone down in my ear and I want to cancel the contracts on the data packages as they do not help me in my business at all I am forced to hot spot all the time. Absolutely shocking experience.
