Bad service

I upgraded my contract on Sunday in Alberton branch, the guy who assisted me then provided me with a new sim card which aparently will be receiving an amount of R60, as that was promited. inserted the sim card on Sunday it did not work i then went to Vodacom Eastrand mall to tell them the simcard still not working they told me it will work after 24 hours, its more than 48 hrs later the simcard is not working. i cannot be walking back and forth to Vodacom shops!!!!!
