Line has been locked for 2 weeks, and no solution is in sight

<p>When I call Vodacom they say it's because it's a new system and there's problems with the system. My line is locked because my credit limit has been reached. They can unlock the line and it works for 1 day, and the next day it's locked again. and nobody can even raise the credit limit for me. So for 2 weeks now I can't do anything with my phone and they can't even tell me when the issue will be resolved. So why am I paying for a contract which I can't even use.</p>
