Data Share Activation

I am a contract customer and have tried for a week now to activate Data Share via all channels available to me. I tried MTN Active, called 808 support line and went to the MTN shop in the Rosebank Mall. The Data Share service is showing as being active across both my Dualcall SIM cards but still it doesn't work.<br> <br> When dialling the *141*5# USSD to setup sharing I receive an error: \You are not sharing any internet bundles. To set up data share please contact your service provider."When I call 808 the agent merely says that data share is active"
