Jet store Cresta the worse service ever

I am so ****ed. I purchased an e-gift card at Jet Cresta of which I was told will take 5min to come as a SMS on my phone. A whole hour later and I am still at this store and no one can cancel this or provide me with the gift card I bought.

Been here waiting for their IT to resolve this matter and my child is tired and hungry and the party she's supposed to go to ends at 5pm and we are still not assisted.

The worse service ever. I will never come back to this store and I will spread the word with my family and friends to never come to any Jet store ever again.
