Worst service ever

<p>I upgraded my contract cellphone from a samsum s5 to an iphone 6s. Due to the fact that the iphone uses a nano sim i had to do a sim swap ftom my micro sim. To my suprise my sim card is still not activated and i have been calling them n not gettimg any assistant.i went to the store in witbank and the lady didnt even have a clue on what to do. It is a simply thing to do really. Activate my dam sim card how hard can it be really. If this is not resolved in the next 6 hours i am canceling this contract.mtn sucks big time.</p>
