Access to account- Numerous requests

I have been phoning MTN call center to find out what phones are available on my Husbands account for our upgrade and was told that they need to speak to the account holder first before they can give me this info.<br> My husband requested in the K90 store that my name be added to the contact persons for the account, after realizing that this was not done he then called the call center and requested on more than 3 occasions already that this can be resolved and every time I phone they still give me this same story. I just want to know what else needs to be done because it is not once or twice that this happened. I told the lady at the call center to listen to their voice recordings of previous conversations, then she would hear my husband asked this before and again it was not done. I was informed it would take very ling to get these recording
