Charged R20k for data & phone locked for no reason

So I had 4gb of data on my phone and planned to do a lot of downloading thus bought about 12gb more. After confirmation that my data had gone through I began downloading.<br> <br> Later in the day my vodacom bill had reached 20k and my data had been untouched. Even better my phone was locked. Called in and was told that my data bundle had been activated, and then deactivated due to an error. They are investigating but there is no way in hell I am paying the out of bundle rate.<br> <br> Secondly my phone is locked. All fair, I call in and ask to raise my limit so I can use my phone and am told my mandatory call limit is in play because my account is less than 7 months old. My account is actually more than a year old but for some reason vodacom are unable to change this setting on my phone. This is the 5th month in a year I have been unable to to use my phone and i am pretty certain they will not be able to activate it before the end of the month when it will magically reset. Bear in mind in previous months I have paid money in to get my account to 0 and they have been unable to unlock the phone.<br> <br> Please prove me wrong vodacom and demonstrate some competence.
