Data not allocated and IP blacklisted?

<p>I have been struggling with my My gig 10 for the last 8 months. Data not being allocated at the beginning of the month. Endless calls to Vodacom call centre. Not being assited and then the call is transferred to someone and the call is dropped. I dont know what to do?</p> <p> </p> <p>and my emails are not going through to one of my biggest customers. After a lot of Tests and talks with IT. My Ip address from Vodacom seems to be blacklisted ??? Of course there is no one at Vodacom that can assit with queries that actually requires some technical knowledge. </p>
