Soft lock

I upgraded my existing contract.The account had a bill limit of R500.00 set on it. The data was running on the background updating all the apps while i left the phone on charge as it was new. I got a message from Vodacom that i have exceeded my limit. When i called Vodacom they informed me that because of that my account has been softlock. I had 769 minutes available to me as well as 400 sms an yet i couldnt make a call because if the limit being exceeded. When i questioned why this , i was advise that they would allow the data to continue as this would be out of bundle rates. I challenged that ethic and asked if i had set a limit on my account not to exceed it how could they still allow it to go over which meant the limit meant nothing. This another way how Vodacom makes money because of this loophole. One of Shameel Joosubs articals read that data usage accounts for 33.4% of the group revenue. What is the use of setting a limit on your account if they can still allow it to go over.<br> They strategy is to get people to use more smart phones and in that way to use more data at the clients expense to grow the book .i have not even used the device at the time of this data bill.
