Terms of contract/number transfer not fully explained

Good day,

Two weeks back, my husband and I went to a Vodacom shop in Forrest Hill Mall, where a friendly lady assisted us with renewing a contract and getting a new one. However whilst getting a new contract for the cellphone I received, my number was then converted in the contract, the lady did ask me, however what she failed to do was fully explain what that meant for me, since that number ( ********** 986) was always used by me, now I cant even do anything without my husband, as the number now has been shifted from me to him.

What I need is this transfer to be reversed, I need my number back and I cant continue in the way that been done..
