sim swap never ending

i bought a contract from the vodacom data store on sunday the 3 April and i asked and paid for a sim swap they sed it would take 2-24 hours i went in on the 4 April at 3pm which would be 26 hours after the purchase of the phone and the sim swap had not been done , i went in to the store and a photo copy of my original sim was unclear but they had not notified me of this after this Lauren sed it would be complete with in 4 hour which it had not . i called their call center and queried about the issue and i was informed that no sim swap had happened and that i was given the wrong sim card so i will have to go back down for the 3rd (including the time i purchased the phone ) to their store and sort this issue out . the issue is costing me time and money i cant afford to lose as i am a student .<br> regards <br> unhappy Client
