<p>We are desperately trying to get integrated data sim cards, but none of your stores has stock apparantly. We are sent from store to store, just to get there to hear that they dont have stock. The imbecile at Cresta gave me blue sim cards instead of the correct white ones, and waisted an hour of my time registering these..... Just to have to find out that the blue ones will never work!! How difficult can this be??????? Our internet is down on a weekly basis lately, so I need these simcards URGENTLY! YOUR ARE WAISTING MY TIME AND PETROL, AND BECAUSE OF YOUR PATHETIC SERVICE I END UP HAVING TO BUY DATA FROM OTHER SUPPLIERS AT ONE HELL OF A PREMIUM!!!!!</p>
