No one have a clue what Data Share is

It's been more than a week now since I first complained about my phone not being able to receive any data while it's linked to my Data Share contract.<br> <br> I've spoken to lots of people, 1555, 808, Facebook, MyBroadband,etc... No one seems to be have a clue how to help me and most doesn't even know what Data Share is.<br> <br> I've got a data contract which has Data Share enabled. I've linked my main number to that Data Share contract and it worked perfectly for a long time. Then all of a sudden it just stopped working. My main number is connected but it can't send or receive data. I then delinked it from the Data Share contract and it worked fine. As soon as I link it again it doesn't work. So it is definately not a setting on my phone like everyone is telling me.<br> <br> Then I linked my secondary number to the Data Share contract to see if there isn't a problem with the Data Share contract. The secondary number is still working perfect.<br> <br> I don't know who to call anymore because everyone is saying something different. One person (a data expert at MTN Tyger Valley) even told me that it could be my wifi. I mean, come on. Data Share has nothing to do with wifi.<br> <br> Please help. I'm desperate.
