Data Share Issues

When attempting to add a number on to my Data Share following the *141*5# method I receive the following error: \This request is not allowed. Please contact MTN customer service ". I then contacted MTN upon which the agent said to me that they can not assist me due to Data Share being \""self-service\"". How am I then suppose to have this matter rectified if my service provider can't assist me and their network error referring me to them? <br> <br> I also attempted using the MTN Active web site to add the respective MTN number that I want to share my data with. Once again I get an error. The error that I'm getting is: \""You can not link yourself to this Data Share Plan\"". The number I want to share my data with used to be a contract in my name but has been converted to Pay As You Go more than a year ago. Can MTN please assist me in sorting this matter out??? """
