Vodacom specials and admin fee

<p>I have a problem with the fact the vodacom takes an admin fee every time you make an upgrade even though you are already a customer.</p> <p> </p> <p>I also recently upgraded to a wifi modem and now saw that they have a deal where you can get 5G on your modem but because I took out my contract earlier this year, I cannot convert to that deal.</p> <p> </p> <p>I would like to know why? Companies like Cape Union Mart give you the money back when a special comes up regarding the same item you bought.</p> <p> </p> <p>Why does Vodacom not adhere to such ethical policy?</p>
