Charged out of bundle with active data bundle

<p>I noticed the last few weeks that the bill on my account is getting more and more. I went on the vodacom website and noticed it was from out of bundle data usage that i'm charged even though I have a active data bundle on my account that has not expired. So using any internet on my cellphone gets charged out of bundle and it deducts from the current data bundle balance. I request for the problem to be fixed and also for the excessive out of bundle data charges to be removed from my account. I did log a service request by calling Vodacom but this is urgent as all data gets deducted from the data bundle and added to the account. I have turned off my data that I acctually need to avoid getting charged more.</p> <p>Please assist urgently?</p>
