Lines Blocked For No Reason

My cell line was blocked on the 26.01 for no reason - after phoning *** - i received an sms to say my phone was unlocked.<br> This morning 02.02 my phone was locked for no reason again.<br> I have a top up contract and they say i exceeded my credit limit - what bull - how can i exceed a credit limit on the top up contract.<br> My data contract is also 2 gig top up - so how can i exceed that as well.<br> I am on the *** for the last 30 minutes and they don't even answer their phones.<br> If this is the service i am going to get from Vodacom - i have been a customer for the last 10 years - then i think now its time to change to another service provider.<br> Will someone from Vodacom please respond to me urgently - i use my phone to make a living and support my family<br> Very unhappy customer<br>
